Limelight

Limelight (produced lahym-lahyt)

(1) In the lighting systems of live theatre, prior to the use of electricity, a lighting unit for spot-lighting the front of the stage, producing illumination by means of a flame of mixed gases directed at a cylinder of lime and having a special lens for concentrating the light in a strong beam.

(2) The light produced by such a unit (and subsequently by lights using other technology.

(3) In theatre slang (1) a lighting unit (also clipped to “limes”), especially a spotlight & (2) by extension, attention, notice, a starring or central role, present fame (source of the general use of the word).

(4) The centre of attention, interest, observation, or notoriety.

(5) As “limelight dress”, a designed to make the wearer the “centre of attention”.  Of late, “limelight” has been applied also in high street fashion to refer to garments made with neon-like fabrics which resemble a color under a bright light.

1826:  The construct was lime + light.  Lime (in this context) was from the Middle English lyme, lym & lime, from the Old English līm, from the Proto-Germanic līmaz, from the primitive Indo-European sley- (smooth; slick; sticky; slimy).  It was cognate with the Saterland Frisian Liem (glue), the Dutch lijm, the German Leim (glue), the Danish lim (from the Old Norse lím) and the Latin limus (mud).  In chemistry, the word described any inorganic material containing calcium (usually calcium oxide (quicklime) or calcium hydroxide (slaked lime).  In literary or poetic use, it was used of any gluey or adhesive substance, usually in the sense of “something which traps or captures someone” and sometimes as a synonym for birdlime.  It was used as a verb to mean (1) to apply to some surface a coasting of calcium hydroxide or calcium oxide (lime) & (2) to smear with birdlime or apply limewash.

Lime (chemical formula: CaO) is composed primarily of calcium oxides and hydroxides (typically calcium oxide and/or calcium hydroxide) and the origin of the word lies in its early use as building mortar (because of its qualities of sticking or adhering).  It was the interaction of lime with other substances which lent the concrete mixed in Ancient Rome (known to engineers as “Roman concrete”) unique properties that made it remarkably durable and long-lasting (though despite the legend, it was no more “sticky” that other concrete using the same quantity of lime).  A critical ingredient in Roman concrete was a type of volcanic ash called pozzolana (abundant in the environs of Rome) which was mixed with lime and small rocks or rubble to create a paste that could be molded into various shapes and sizes.  What created uniqueness was the chemical reaction between pozzolana and lime when the mix was exposed to water, this creating a mineral called calcium silicate hydrate, the source of Roman concrete’s durability and strength.  Unusually, it was able to harden underwater and for centuries resist the effects of saltwater (indeed such exposure triggered a kind of “self repair” reaction), making it ideal for building structures like harbors and aqueducts and, in a happy coincidence, the easy accessibility of pozzolana meant Roman concrete could be produced at a lower cost than other building materials.  Engineers note the chemistry but maintain the slang “sticky concrete” remains appropriate because its durability meant the stuff is still “sticking around”, centuries after other forms of concrete have crumbled to dust. 

Light (in this context) was from the Middle English light, liht, leoht, lighte, lyght, & lyghte, from the Old English lēoht, from the Proto-West Germanic leuht, from the Proto-Germanic leuhtą, from the primitive Indo-European lewktom, from the root lewk- (light).  It was cognate with the Scots licht (light), the West Frisian ljocht (light), the Dutch licht (light), the Low German licht (light) and the German Licht (light) and related also to the Swedish ljus (light), the Icelandic ljós (light), the Latin lūx (light), the Russian луч (luč) (beam of light), the Armenian լույս (luys) (light), the Ancient Greek λευκός (leukós) (white) and the Persian رُخش‎ (roxš).  The early uses (in this context) all were related to the electromagnetic radiation in the spectrum visible to the human eye (ie what we still commonly call “light”).  Typically, the human eye can detect radiation in a wavelength range around 400 to 750 nanometres and as scientific understanding evolved, the shorter and longer (ultraviolet light and infrared light) wavelengths, although not visible, were also labeled “light” because, as a matter of physics, they are on the spectrum and whether or not they were visible to the naked eye was not relevant.  “Light” in the sense of illumination was literal but the word was also productive in figurative and idiomatic generation (the “Enlightenment”; “leading light”; “negative light”; “throw a little light on the problem”; “bring to light”; “light the way” etc).  Limelight is a noun & verb, limelighting is a verb, limelighted & limelit are adjectives and limelighter is a noun; the noun plural is limelights.

Three exemplars of the art. 

The term “limelight dress” was coined to describe a garment designed to attract the eye (or a photographer's lens), making the wearing the “centre of attention” in the manner of a stage performer in the limelight: Rita Ora (b 1990, left), Ariel Winter (b 1998, centre) and Lindsay Lohan (b 1986, right) illustrate the idea; while there are often commonalities in the way designers do these things, there are many variants.  It has in recent decades become less easy to achieve the “limelight dress effect” because of the mainstreaming of the “nude dress” and it may be that a more modest cut, if well executed, might work better for clickbait purposes, just because of the novelty.  Rita Ora with some aplomb wore the dramatic gown designed by Donna Karan (b 1948) at the 2014 MTV Video Music Awards in 2014 and while it was much admired, a similar creation in the same scarlet by Alexandre Vauthier (b 1971) Couture created a sensation when worn by Bella Hadid (b 1996) at the 2016 Cannes Film Festival.  Perhaps the ultimate “limelight dress”, it remains still probably the dress of twenty-first century.     

In the limelight: In a marquisette gown, Marilyn Monroe (1926–1962) sang Happy Birthday Mr President to John Kennedy (JFK, 1917–1963; POTUS 1961-1963) at a Democratic Party fundraiser at New York's Madison Square Garden on 19 May, 1962, ten days before his actual birthday.  Within three months, she would be dead.

The dress became one of the best-known garments of the Marilyn Monroe cult and it re-appeared at the 2020 Met Gala in New York City, worn by Kim Kardashian (b 1980) complete with blonde hair for the occasion.  It couldn’t be expected to cause quite the same stir as sixty years earlier because, cut from a sheer, silk marquisette that almost exactly matched Ms Monroe’s skin-tone, the 2,500 hand-sewn rhinestones intricately were positioned to respond to the particular gait she chose that evening and, under the limelight in the darkened amphitheatre, as she moved, the crystals sparkled and the dress came alive.  It was quite a design.  In the hard, white light of the Met Gala’s red carpet, it couldn’t be expected to work the magic it did all those years ago; not shimmering in the darkness, it seemed lifeless and perhaps it would have benefited from the contrast her lustrous natural hair would have lent but Ms Kardashian wore it well, attracting admiration (and criticism from the usual suspects) too for the reasonable achievement of in three weeks shedding a reputed 16 lbs (7¼ kg) to ensure a (close to) comfortable fit.

Limelight was the common name for the Drummond light (or calcium light), a lamp of then unprecedented luminosity created by the burning of calcium oxide (lime).  The process of creating light by burning lime augment by oxygen & hydrogen had been invented in the early 1920s and, generating an intense white light, it was developed in 1925 for use in mining and surveying by Scottish army engineer Captain Thomas Drummond (1797-1840) and soon adopted for lighthouses although it became famous from the use in live theatre where directional spot-lights were used to illuminate the principal actors on stage and although the technology has moved on, in theatre, film & television production, catwalks etc, “limelight” is still often used to describe both the physical lighting equipment and the effect produced.  In popular entertainment, limelight came into use in the UK in the mid-1830s and, cheap to produce and easily exported, were soon in use around the world, even the military finding them useful, the army to assist the targeting of artillery (an early example of applying technology to fire-control systems) and the navy found they were vastly more effective than any other spotlight.  Limelights remained in widespread use until replaced by electric devices in the late nineteenth century but in some far-flung outposts of the British Empire, they were still in use even after World War II (1939-1945).

Although "glare" isn't vested with quite the cachet of "limelight", Ms Lohan illustrated how the catwalk was but a state of mind, pairing a white bandage dress (it’s not clear if wearing the color the Bible associates with purity influenced the judge but channelling the fashion choice of the 24 elders in Revelation 4:4 and the Roman Catholic pontiff may have helped) with a pair of Chanel 5182 sunglasses.  Speculatively, it’s at least possible a strut under the limelight on the catwalk wouldn’t have had the same simulative commercial effect as the stroll to a hearing, the the US$575 Glavis Albino dress from Kimberly Ovitz's (b 1983) pre-fall collection selling-out worldwide that very day.

New York Post, 11 February, 2011: Rupert Murdoch's (b 1931) editors always have a feeling for a good headline.  On X (then known as Twitter), Ms Lohan observed of the coverage: “What I wear to court shouldn't be front page news.  It’s just absurd.”  However, as a studious student of the modern media, she would have understood the place of absurdity in tabloid journalism and doubtlessly accepted it was best to work with the world as it is than worry too much about how it ought to be.

From the idea of the character on stage being highlighted by the limelight came the figurative use of the phrase “in the limelight” (noted since 1877) to refer to anyone on whom attention is focused.  From this evolved the related and self-explanatory phrases “steal the limelight”, “bask in the limelight” & “hog the limelight”, all from the world of theatre but later adopted as required just about anywhere (sport, corporate life etc).  “In the limelight” tends to be used only positively; those who are the focus of attention for reasons such as being accused of committing crimes or some transgression which might lead to cancellation are usually said to be “in the glare”.

1970 Plymouth Hemi 'Cuda in Limelight (left) and 2023 Dodge Challenger SRT Hellcat Redeye Jailbreak in Sublime (right).  Although today much prized, Chrysler's E-body pony cars (Plymouth Barracuda (& 'Cuda) and Dodge Challenger (1970-1974) were a financial disaster but, as Dodge's (2008-2023) revival proved, the styling was spot-on.   

Like other US car manufacturers in the strange, cultural twilight zone that was the dying days of the Johnson administration (Lyndon Johnson (LBJ, 1908–1973; VPOTUS 1961-1963 & POTUS 1963-1969)) and the first term of Richard Nixon (1913-1994; US VPOTUS 1953-1961 & POTUS 1969-1974), Chrysler had some history in the coining of fanciful names for colors dating from the psychedelic era.  What came from the once staid corporation included “Plum Crazy”, “In-Violet”, “Tor Red”, “Limelight”, “Sub Lime”, “Sassy Grass”, “Panther Pink”, “Moulin Rouge”, “Top Banana”, “Lemon Twist” & “Citron Yella”.  Although it may be an industry myth, the story told is that “Plum Crazy” & “In-Violet” (lurid shades of purple) were late additions because the killjoy board refused to sign-off on “Statutory Grape”.  Plymouth labelled their lime green “Limelight” while Dodge used “Sub Lime”.  The acid-themed shades so associated with the era vanished from the color charts in the early-1970s, not because of changing tastes but in response to environmental & public health legislation which banned the use of lead in automotive paints; without the additive, production of the bright colours was prohibitively expensive.  Advances in chemistry meant that by the twenty-first century, the look could again be achieved without the addition of lead so Dodge revived psychedelia for a new generation although “Sub Lime” became “Sublime”.  There was however, still a price to be paid, the new, environmentally less lethal, “Sublime”, “Red Octane”, “Sinamon Stick” and “Go Mango” all costing an additional US$395 while the less vivid shades listed at US$95.

Marquisette

Marquisette (pronounced mahr-kuh-zet or mahr-kwuh-zet)

A lightweight open leno weave fabric of cotton, silk etc; very popular under the Raj.

1907: From the French, diminutive of marquise (a marchioness), from the Medieval Latin marchionissa (feminine form of marchion) from Late Latin marcha, from which Frankish picked up markōn (to mark, mark out, to press with the foot).  The Proto-Germanic was markō (area, region, edge, rim, border).  Marquisette fabric is constructed using a leno weave and was originally made only from silk for use in bridal wear and evening gowns.  More commonly nowadays, it is made from cotton, wool or synthetic fibres and is used for drapes and mosquito nets.  Marquisette, along with voile, was a robing fabric especially suitable for travel and for draping over other dresses.  Early in the twentieth century, Deliniator magazine adopted the light, limp fabric for the newly fashionable directorie look.

Marilyn Monroe, President Kennedy and the marquisette dress

In a marquisette dress, Marilyn Monroe (1926-1962) sang happy birthday Mr President to President John Kennedy (JFK, 1917-1963; US president 1961-1963) at a Democratic Party fundraiser at New York's Madison Square Garden on 19 May 1962, ten days before his actual birthday.  Within three months, she would be dead.

An impressive piece of structural engineering (so body-hugging Ms Monroe had to sewn into it) and an eye-catching design, the dress was cut from a sheer, flesh-colored silk marquisette, adorned with 2500 hand-sewn (and intricately positioned) rhinestones and the famously sultry performance did nothing to dispel rumors the two might be having an affair.  In 1962 it cost US$1,440.33 (equivalent to some US$10,000 in 2022) and it remained part of Ms Monroe's estate until sold at auction by Christie's in 1999 for US$1.3 million.  Subsequently, it was purchased in 2016 for US$4.8 million by Ripley's Believe It Or Not Museum in Florida. 

RFK, Marilyn Munroe & JFK.

The first conceptual sketch of the dress was the debut project of US fashion designer Bob Mackie (b 1939) who two years earlier had left the Chouinard Art Institute to work for French costume designer Jean Louis (1907-1997) and year later, he revealed to Vogue magazine that until the pictures of the Madison Square Garden performance were published, he had no idea of the use to which his sketch was to be put.  Marilyn Munro was certainly aware of the impact the translucent look would have and was seeking a “work-around” to the problem of her employer (Twentieth Century Fox) not permitting her to be dressed too revealing in films.  Having just lost weight and concluded she was looking better than ever, she wanted an outfit with what Mackie called “the wow factor” and that she certainly got.  Sixty years on, dresses which approach functional nudity are commonplace but in 1962 the clinging, shimmering creation which moved with her, caused a sensation.  The garment is also a reminder of the way history unfolds according to the chance interaction of events.  Had JKF not won the 1960 presidential election "by an electoral eyelash", the song would doubtlessly never have been performed.  Marilyn Munroe would not have dressed as she did to sing happy birthday Mr President to Richard Nixon (1913-1994; US president 1969-1974).

Remarkably, despite being in the limelight that evening, Ms Monroe purchased five tickets (at US$1000 each) to the event because it was the only way to guarantee her attendance at the private supper which followed.  At the after-party she enjoyed a number turns on the dance floor with the president’s brother, Robert Kennedy (RFK, 1925–1968; US attorney general 1961-1964) although it was reported she left with JFK via a basement corridor and a private elevator to his suite at the next-door Carlyle Hotel, returning the next day to Los Angeles.  There, according to her biographer, she was contacted by one of his aides telling her not to again contact him.  They would never meet again and within three months, she was dead.

Kim Kardashian, Met Gala, New York, 2020.

At the 2020 Met Gala, Kim Kardashian (b 1980) wore the famous marquisette dress.  It couldn’t be expected to cause quite the same stir as sixty years earlier because, cut from a sheer, silk marquisette that almost exactly matched Ms Monroe’s skin-tone, the 2500 hand-sewn rhinestones were intricately positioned to respond to the particular gait she chose for that evening and, under the limelight in the darkened amphitheater, as she moved, the crystals sparkled and the dress came alive.  It was quite a design.  In the hard, white light of the Met Gala’s red carpet, it couldn’t be expected to work the magic it did all those years ago and, not shimmering in the darkness, it seemed lifeless and perhaps it would have benefited from the contrast her lustrous natural hair would have lent but Ms Kardashian wore it well, attracting admiration (and criticism from the usual suspects) too for the reasonable achievement of shedding some 16 lbs (7¼ kg) in three weeks to ensure a comfortable fit.  Digesting the implications of that, keen-eyed fashionistas noted the vintage white coat which Ms Kardashian kept strategically positioned below the small of her back for the ritual walk to and up the staircase, some taking to Twitter to wonder if it was there to conceal that things were quite fully done-up.

Marilyn Monroe, Madison Square Garden, New York City, 19 May 1962.

The theory is plausible; it’s always been known that in 1962, Ms Monroe had to be “sewn-into” the dress just before the performance.  The day after the Met Gala, photographs circulated purporting to show Ms Kardashian with a generously sized, pear-shaped lacuna between the seams, accompanied with the accusation that the images showing things done up had been digitally modified and the haters were certainly out, one distressed soul lamenting that for Ms Kardashian to wear the dress "...was an absolute disgrace, a tacky photo opportunity" and that "...one of the most important items of clothing in history, is now tainted with the stain of the Kardashians."  There are people who do take pop-culture very seriously.  The green dress she changed into after her ascent had similar lines (and perhaps slightly more generous dimensions) but was certainly done-up and anyway, in either, she looked gorgeous.  The Marilyn Monroe cult shows no sign of losing its luster and it was her Lindsay Lohan channeled for both her photo-shoot by Bert Stern (1929–2013) for New York Magazine in 2008 and her appearance in the January/February 2012 issue of Playboy magazine.

Neon

Neon (pronounced nee-on)

(1) In chemistry, a rare, colorless, odorless gaseous element; an inert gas (the second in the noble group) occurring in trace amounts in the atmosphere.  It glows reddish orange when electricity passes through it, as in a tube in an electric neon light, hence the industrial use in illuminated signs & lights although it’s used also in refrigeration because of the helpfully low melting & boiling points.

(2) A neon lamp, tube or device, in the singular or collectively; made of or formed by a neon lamp or lamps.

(3) A sign or advertising display formed from (or emulating) neon lamps.

(4) Of, relating to, or characteristic of an urban area brightly lit during hours of darkness and often associated with popular forms of entertainment.

(5) As in the phrase “in neon”, or “in neon lights”, adding emphasis to something (sometimes used derisively).

(6) Any of a range of bright, lurid colors, used particularly in fashion (lipsticks, nail polish etc) and as hair color products.

(7) As neon tetra (Paracheirodon innesi), a freshwater fish of the characin family (family Characidae) of order Characiformes, native to the Amazon basin in South America.  Because of its vivid coloring and robustness, the neon tetra is one of the most popular tropical fish in home aquariums.

1898: From the Ancient Greek νέον (néon), neuter of νέος (néos) (new; young), from the earlier νέϝος (néwos), from the Proto-Hellenic newos, from the primitive Indo-European néwos.  From the same source, English (and other languages gained the prefix –neo which was often used to form clade or taxonomic names indicating more recent branching than a morphologically or otherwise similar group.  The prefix neo- was from the Ancient Greek prefix νεο- (neo-), from νέος (néos) (new, young).  In organic chemistry it (1) had the specific technical meaning “having a structure, similar to that of neopentane, in which each hydrogen atom of a methyl group has been replaced by an alkyl group” and (2) a newly-discovered or synthesized variant of an existing compound.  The synonyms (in the sense of something new) were ceno- & nov-, the less used antonym paleo-.  Many words have been prefixed with neo- and not exclusively to indicate something wholly novel but increasingly to describe a revival or new variation of something including (1) in architecture: neo-classical, neo-gothic etc, (2) in economics: neo-liberal, neo-Keynesian etc, (3) in politics: neo-Nazi, neo-conservative, neo-fascist etc and (4) in religion: neo-evangelicalism, neo-Hasidism etc.  In chemistry, the meaning is quite specific but in general use the synonyms include blazing, brilliant, glowing, lambent, luminous, radiant, shining, vivid, flashing, glitzy, glossy, razzle-dazzle, effulgent & gleaming.  Neon is a noun & adjective; the noun plural is neons.

Sohio “Neon Patrol” in action, Cleveland, Ohio, July 1938.  Technicians from the Neon Patrol would travel between the company’s retail outlets, servicing the neon signage and effecting repairs when required.  The truck is an International D-15 with a special body.  The D Series (1937-1939) was a range of light, medium & heavy-duty trucks, easily distinguished from the more rectilinear C Series (1934-1936) by the curvilinear lines and the two-piece V-shaped windshield.  The line was replaced by the K (1940-1946) & KB Series (1947-1950).

The Standard Oil Company (Ohio) was a US petroleum company which operated between 1870-1987 and Sohio was one of a number of separate entities created in 1911 after the Standard Oil corporate trust (1882-1911) was broken up.  Standard Oil and British Petroleum (BP) in the 1960s entered into an intriguing (and tax-friendly) arrangement whereby BP gradually would increase its stake in Standard Oil, culminating eventually in acquisition.  Sohio as a corporate identity ceased operations in 1987 but BP continued to sell gas (petrol) under the brand until 1991, the name formally retired when the branding on the last Sohio gas station was replaced with BP signage.

Neon nail-polish in 5-pack by Casey's Toys (part-number 52123) @ Aus$9.99.

Although in the United States it’s possible for citizens (in some cases children) lawfully to possess military-grade firearms and some truly impressive ordinance, in other fields the government is punctilious in providing people protection.  In 2012, Douglas Schoon (b 1954), Creative Nail Design's (CND) chief scientific advisor, explained that in the US, the manufacture of neon nail-polish was unlawful, although, in what seemed a quirk of the law, the products remain lawful to wear.  However, that apparent anomaly isn’t actually strange or unique to neon nail-polish and reflects a regulatory environment where the need is to certify the safety of both the components and the processes used in the manufacturing process.  There are no concerns about the safety of the finished product, skin and nails anyway a most effective barrier and the nature and volume of fumes breathed in by consumers “doing their nails” would substantively be identical to that of other nail-polishes.

Coffin-shaped nails in neon-green.  These are actually "press-on nails".

Neon polishes are prohibited simply because the colorants have never been officially registered with the US Food & Drug Administration (FDA).  Mr Schoon explained that “…what determines whether a color is neon is the chemical composition, just as it is with blues and greens”, adding that that any manufacturer could submit neon shades to the FDA, but it’s a costly and time-consuming process which is why many of the lurid shades available in the US, technically, are not neons.  Registration is only the first step in securing FDA approval and few small-scale manufacturers have the resources to go through a process from which others would gain equal benefit.  Imported neon polishes appear on many shelves but it’s not known if unlawful, small-scale manufacturing is being undertaken somewhere in the US.

As an adjective used of colors, neon refers to the quality of brightness rather than the red-orange colour which is the particular property of neon gas under electrical stimulation.  Thus, a “neon color” (or simply “neon”) is anything bright, lurid and used in clothing, accessories & enhancements (lipsticks, nail polish etc) or hair color products.

"Neon" advertising displays, Piccadilly Square, London, 1967.

Neon was discovered in 1898 by British chemists Sir William Ramsay (1852–1916) and Morris Travers (1872–1961) while working in their London laboratory during a series of experiments which also uncovered krypton & xenon, the other two residual rare inert elements remaining in dry air after nitrogen, oxygen, argon and carbon dioxide are removed.  In normal conditions a colorless, odorless & inert monatomic gas, it has about two-thirds the density of air and is noted for its emission in the spectrum of bright red when exposed to electrical current.  Although one of the known universe’s most common elements (fifth behind hydrogen, helium, oxygen and carbon), it’s rare on Earth, existing only in trace amounts in the atmosphere, attributable to it being highly volatile and thus never forming compounds which assume any solidity.

It needs thus to be extracted from air by an industrial process so is relatively expensive, its industrial uses limited to some specialized applications in refrigeration (by virtue of its low melting & boiling points) and the famous “neon lights” most associated with advertising and signage, the first of which was released in 1913, the term “neon sign” dating from 1927.  The distinctive bright red (tending to orange) light distinguished the first neon signs (created with curved neon-tubes) and in the narrow technical sense these are the only true “neon-lights” because tubes which generate other colors are made using either other noble gases or are instances of fluorescent lighting.  In hidden use, neon is also a component of various electrical devices including vacuum & wave tubes, current indicators and lightning arresters.

Late twentieth (left) and early twenty-first (right) century Tokyo after dark: now less pink, more blue.

For decades, pink was the dominant color in the night-time Tokyo streetscape but in the twenty-first century observers began noting a shift to something darker.  The change is attributed not to the nation’s post 1989 slump in economic growth (the so-called “lost decade” of the 1990s apparently never having ended) but the development in 1993 by Japanese-American engineer Shuji Nakamura (b 1954) of a high-efficiency blue LED (light emitting diode) using gallium nitride (GaN) as the semiconductor material.  While green and red LEDs had for decades been in use, blue had proved elusive because the industry lacked a material suitable (and sufficiently cheap) to use at scale.  Nakamura san’s work built on earlier research by Japanese physicists Isamu Akasaki (1929–2021) and Japanese physicist Hiroshi Amano (b 1960) and what the three did was make possible both blue and white LEDs, the latter enabled by combining the blue with phosphors.  In 2014, the three were awarded the Nobel Prize in Physics.

Lurid neon hues began to fade from the roads after being banished from the automotive color charts in the mid 1970s and while it can be debated if that was an aesthetic loss, it certainly made the option lists less linguistically interesting.  Like other manufacturers, Chrysler had some history in the coining of fanciful names for colors dating from the psychedelic era of the late 1960s when the choices included Plum Crazy, In-Violet, Tor Red, Limelight, Sub Lime, Sassy Grass, Panther Pink, Moulin Rouge, Top Banana, Lemon Twist & Citron Yella.  Although it may be an industry myth, the story told is that Plum Crazy & In-Violet (lurid shades of purple) were late additions because the killjoy board refused to sign-off on Statutory Grape.  Plymouth called their lime green Limelight while Dodge used Sub Lime.  That the colors vanished during the 1970s was not because of changing tastes but in response to environmental & public health legislation which banned the use of lead in automotive paints; without the additive, production of the bright colours was prohibitively expensive.  Advances in chemistry meant that by the twenty-first century brightness could be achieved without the addition of lead so Dodge revived psychedelia for a new generation although Sub Lime became Sublime.  There was still a price to be paid however, Sublime, Red Octane, Sinamon Stick and Go Mango all costing an additional US$395 while the less vivid shades listed at US$95.  The resurrected "neon look" proved popular although only within the high-performance niche, most of the market preferring more "dignified" tones such as black, white, silver and many variations of gray although there's still the odd malcontent who orders blue or red.  On the street, Chrysler's bright colors were all the more noticeable because the mainstream-market preference now tends to white, silver, black and grey.  

2015 Dodge Challenger SRT in Sublime (code FB).  Literalists should note this is NOT what Greta Thunberg (b 2003) meant when she spoke of "green vehicles".

There was of course once a time when the term “green vehicle” had a simple, unambiguous meaning but were a driver to contest a parking ticket, the outcome might depend on how a court would apply the “Vagliano rule”, established by the House of Lords in Bank of England v Vagliano Bros (1891) AC 107.  The Vagliano rule is a principle of statutory interpretation and holds that when interpreting a statute, courts should start by considering the natural meaning of the words in the statute itself, without referring to previous case law or historical background, unless the language is ambiguous.  The rule is of such significance because it prioritizes the literal and ordinary meaning of words over any interpretation which could be derived if other factors are allowed to intrude.

In his judgment, Lord Herschell (Farrer Herschell, 1837–1899; Lord High Chancellor of Great Britain 1886 & 1892-1895) wrote: “I think the proper course is, in the first instance, to examine the language of the statute and to ask what is its natural meaning, uninfluenced by any considerations derived from the previous state of the law, and not to start with inquiring how the law previously stood, and then, having ascertained that, to see whether the statute will bear an interpretation which is in accordance with it. If the statute is clear, its provisions must prevail, whatever the previous law may have been. If the statute is ambiguous, then, and only then, may the history of the law be referred to.”  Whether in the 2020s a judge would be persuaded “Green Vehicle” should for this purpose be read-down to permit gas-guzzling V8s (simply on the basis of being painted a certain color), to occupy parking spots allocated exclusively to the machines of which Ms Thunberg would approve may be doubtful but any driver will always be able to find a lawyer willing to run the case and, if heard by a judge fond of a "black letter law" interpretation of things, may enjoy success, at least at first instance.  Presumably, the solution would be for the signs to read: "GREEN" VEHICLES, the semiotics of the inverted commas conveying the new (non-literal) meaning.

Pre-900: From the Middle English noun shadwe, shadu, shadue, shadowe shadow, from the Old English sċeaduwe, sċeadwe & sceadu, the oblique case forms of sċeadu (shadow, shade; darkness; protection).  The Middle English verbs were shadwen, shadwe, shadu & shadue (to shade, provide shade, cast a shadow, protect), from the Old English sceadwian (to cover with shadow, protect) (all derivative of the nouns), from the Proto-West Germanic skadu, from the Proto-Germanic skadwaz (shade, shadow), from the primitive Indo-European skeh & ḱeh- (darkness).  Contemporary forms included the Old Saxon skadowan & skadoian and the Gothic (ufar)skadwjan (to (over)shadow).  Similar forms in other Germanic languages included the Old Saxon skado, the Middle Dutch schaeduwe, the Dutch schaduw, the Old High German scato, the German schatten and the Gothic skadus (shadow, shade).  Shadow is a noun, verb & adjective, shadower is a noun, shadowdy, shadowless & shadow-like are adjectives; the noun plural is shadows.

The shadow-box was a protective display case, usually in the form of interlocking squares and wall-mounted was first advertised in 1892.  The term shadow-figure was a synonym of silhouette, dating from 1851.  Eye-shadow was a term invented for the commercial products which came onto the market in 1918, providing a convenient packaged product to achieve the look women (and apparently not a few men) had been creating for thousands of years.  Shadow-boxing was first noted in 1906, an update of the earlier (1768) shadow-fight.  The verb foreshadow (indicate beforehand was a figurative form, the idea apparently of a shadow thrown before an advancing material object as an image of something suggestive of what is to come.  It’s familiar also in the forms foreshadowed & foreshadowing and was used as a noun since at least 1831.  Although the meanings were different, in Old English there was forescywa (shadow) & forescywung (overshadowing).  The adjective shadowy was ultimately from late fourteenth century shadwi & shadewy (full of shadows, shaded (and also “transitory, fleeting, unreal (resembling a shadow)”).  From very late in the eighteenth century it conveyed the sense of “faintly perceptible”.  In The Old English there was sceadwig (shady) and the modern alternative is shadowiness but unfortunately, the marvelously tempting shadowous never caught on.  The noun shadowland came from a work of fiction in 1821 and meant “an abode of ghosts and spirits”, adopted from the early 1920s to mean an indeterminate or unhappy place”.  The noun shadowless was from the 1630s and meant literally “no shadow” the implication being of things ungodly or supernatural.

In idiomatic use shadow often appears.  To be a shadow of one's self is to have suffered some trauma meaning one is a lesser person than before.  One afraid of one’s own shadow is one of a skittish, nervous disposition.  If something is beyond a shadow of a doubt it is something certain.  The old expression sanctuary in the shadow of the church was not exactly literal: to seek sanctuary from the agents of the state by entering a church meant one had to pass through the door.  It referred to the noting that church soil in England was under the authority of the pope in Rome, not the King.  To throw (or cast) a shadow over someone is to seek to deny them visibility; to keep them out of the limelight.

1969 Rolls-Royce Silver Shadow.

In continuous production until 1980, the Rolls-Royce Silver Shadow was introduced in 1965 and with over 30,000 (including the less common but substantially identical Bentley T2 variant) built, it remains the Rolls-Royce made in the greatest volume.  Although there was little about the model which was cutting-edge, it was the first truly modern Rolls-Royce, forsaking the separate chassis, drum brakes and styling which used updated motifs from the 1930s; it was the template with which the company would underpin its products for the rest of century.  Although the huge Phantom V & VI limousines would continue to use a separate chassis until 1990, their annual production was measured (usually at most) in the dozens and it was the Silver Shadow and its derivatives which were the company’s bread and butter.  The adoption of unitary construction meant the end of the line for many specialist coachbuilders and some of the relics of the industry were absorbed by the factory, the Mulliner name still used by Bentley to adorn the even more expensive “special order” vehicles the 1% need to convey the message of wealth something "off the shelf" can’t manage.

1967 Rolls-Royce Silver Shadow two-door saloon by James Young (left) and 1971 two door saloon by Mulliner Park Ward (MPW) (right).

However, on the Silver Shadow platform, James Young, one of the last surviving coachbuilders, did build 35 two-door saloons before the business was shuttered in 1968.  The quirk of the James Young Silver Shadows is truly they were just the standard car with the rear-doors removed and the front units lengthened and it suffered because the competition was the two-door designed by Mulliner Park Ward (MPW) which by then was a specialist division within the factory.  With greater resources and access to all the technical data, the MPW effort was more imaginative and judged universally to be more attractive, its “cow-hip” style (nobody ever suggested using the "cokebottle" appellation Chevrolet & Pontiac had a few years earlier made a trend) carried over when the car was in 1971 re-named Corniche and listed as a regular production model.  The Corniche proved the longest-lived of all the Silver-Shadow family, the convertible (even Rolls-Royce eventually gave up calling such things drophead coupés (DHC)) remaining available until 1996.

Applied with different colors in different ways, eye shadow can achieve various effects.  Lindsay Lohan demonstrates.

The archeological evidence suggests eye shadow is one of humanity’s oldest forms of make-up, worn (usually but not exclusively by women) for thousands of years, and the preparations have included oils and a variety of substances to create the desired colours including minerals & vegetable extracts although charcoal is thought to have been one of the most accessible and popular materials.  The usual rationale for applying eyes shadows is that it’s essentially the same technique as chiaroscuro, a trick used by painters, photographers & film-makers to use real & emulated light and dark to achieve the perception of depth.  Because shadows are inherent to the shape of the eye-socket, eye shadow can be use to accentuate or soften the effect and, if applied with expertise, can even alter perceptions of size and shape.  With a sympathetic choice of shade, the color of the eyes can also be used as a contrast, some taking advantage of colored contact lens to create a look impossible with their natural irises.  Done well, there's no other way to describe the combination of eye shadow and purple contact lens that "eye catching".  Eye shadow can draw attention to the eyes, most trying to make them appear larger, more vibrant, or more expressive.  Despite the name, eye shadow is a flexible product and often used to create a visual illusion on body parts such as the cheeks or décolletage.

Shadow Volumes

Example of shadow mapping with Python summarized by FinFET.

In computer graphics, shadow volume is a technique used to render realistic shadows in three-dimensional (3D) renderings which is employed primarily when dynamic, interactive real-time movement is needed, most obviously in gaming.  Essentially, generating shadow volumes involves determining those addresses in a scene which need to appear as shadows, then rendering them accordingly.  The technique relies on the concept of extruding the boundaries of shadow-casting objects to create a "shadow volume" that represents the space occluded by the object.  In static scenes this was always easy (if once time-consuming) to achieve but when objects nwere moving, until recent decades, the graphics capabilities of computers were insufficient for them to be rendered in anything close to being real-time.  The process essentially is:

(1) Determining shadow casters: The rendering engine identifies objects in the scene capable of casting shadows by calculating the object's position and shape and its relationship to the positions of light sources.

(2) Creating shadow volumes: For each shadow-casting object, the engine constructs a shadow volume based on extending the object's silhouette (defined by the address of the boundaries) in the direction opposite to the light source.  The silhouette is determined by the math of the boundaries viewed from the perspective of the relevant light sources.

(3) Intersecting shadow volumes: The shadow volumes are then intersected with other objects in the scene to determine which parts of those need to be inside or outside the shadow.

(4) Rendering shadows: The shadow volumes are assembled, rendered with darker hues or modified shading techniques to simulate the shadowed regions.

Shadow volumes can be implemented using more than one different algorithm, the most commonly used the z-pass and the stencil buffer.  All techniques are computationally intensive and have been made possible by the advances in the sheer power and complexity of modern graphical processing units (GPUs).

The Microsoft Volume Shadow Copy Service (VSS)

The handy Nirsoft Utilities includes a Shadow Copy viewer.

Microsoft introduced Volume Shadow Copy Service (VSS) with Windows XP (2001).  It worked in conjunction with the High Performance File System (HPFS) and allowed for the creation of point-in-time snapshots or copies of files and volumes on a disk.  What was in 2001 still something of a novelty for most users was the snapshots were taken while the files were in use, enabling access to previous versions or the restoration of files to a specific state, even if they have been been modified or deleted.  The process sequence was:

(1) Snapshot creation: VSS creates a snapshot of a volume or individual files on a disk.  This snapshot represents a "shadow" of the data at a moment in in time.

(2) Copy-on-write mechanism: As files are modified or deleted on the original volume, the VSS utilizes a copy-on-write mechanism.  It stores the original data in the snapshot, allowing users to access the unchanged version while the new changes are written to the live volume.  The lag induced by this can be measured with the appropriate but except with the largest files or on a busy network, it’s not usually something which affects the user.

(3) Shadow copy storage: The shadow copies are stored in a separate location on the disk, typically in a hidden system folder. The storage space occupied by is system-managed by the system, older copies automatically deleted as space is demanded for newer versions.

(4) User accessibility: Users can access the shadow copies through various means, most obviously the "Previous Versions" tab in file properties or the "Previous Versions" feature in Windows Explorer. These interfaces allow users to browse and restore files from a previous point in time.

Shadow copies provided one of the first forms of dynamic file backups for most users and were a convenient form of data recovery without the need of third-party software or external devices.  At scale, similar processes are used by software by companies such as StorageCraft’s ShadowProtect which system administrators can configure in a way that the potential data-losses can be minimized to windows as short as a few minutes.  Combined with off-site backups on large capacity media, it’s still a pest practice approach to data preservation.

Lindsay Lohan's strangely neglected film Among the Shadows (Momentum Pictures, 2019) was also released in some markets as The Shadow Within and it's not known what prompted the change (although there was a film in 2007 called The Shadow Within).  Given the two titles under which the film was distributed have quite different meanings, presumably either the title is incidental to the content or equally applicable.  A dark and gloomy piece about murderous werewolves and EU politicians (two quite frightening species), perhaps both work well and no reviewer appears to have commented on the matter and given the tone of the reviews, it seems unlikely there'll be a sequel to resolve things.
