1350-1400: From the Late Middle English tincture (dye, pigment; colour, hue, tint; process of colouring or dyeing; medicinal ointment or salve (perhaps one discolouring the skin); use of a medicinal tincture; (alchemy) transmutation of base metals into gold; ability to cause such transmutation; substance supposed to cause such transmutation)), the construct being the Latin tīnct(ūra) (act of dyeing) + the Middle English -ure (the suffix indicating an action or a process and the means or result of that action or process).  The construct of tīnctūra was tīnc(tus) (coloured, tinged; dipped in; impregnated with; treated”) + -tūra (the suffix forming action nouns expressing activities or results) while tīnctus was the perfect passive participle of tingō (to colour, dye, tinge; to dip (in), immerse; to impregnate (with); to moisten, wet; to smear), ultimately from the primitive Indo-European teng- (to dip; to soak), (source also of the Old High German dunkon (to soak) and the Greek tengein (to moisten).  It was cognate with the Ancient Greek τέγγω (téngō) and from the Latin Modern English has picked up tint, taint and tainture (an obsolete synonym of tincture).  Tincture is a noun & verb, tinct, tincturation, tincturing & tinction are nouns, verbs & adjectives, tinctured is a verb & adjective, tinctorial & tinctorious are adjectives and tinctorially is an adverb; the noun plural is tinctures.  The noun tinctura is listed by most dictionaries as obsolete but it is still in use poetically.

The fifteenth century use by apothecaries to refer to medicinal ointments (the assumption by historians this use was associated particularly with those used to discolor the skin or from being imbued with the essential principles of the substance).  In pre-modern medicine the meaning lingered, the idea of a tincture being a “solution of medicine in a mixture of alcohol” recorded in the professional texts in the 1640s.  In fashion, parchment preparation and then still rare applications such as wallpaper, the word was used to describe a “process of coloring" from early in the fifteenth century.  The verb was derived from the noun and came into use in the 1610s in the sense of “imbue with color”.  Tincturation (preparation of a tincture) was in use by the mid nineteenth century while tinction has been used to mean “preparation for dyeing, coloring matter ready for use” since the 1890s.

Not following the rules: The Lohan family crest.

In heraldry, the “rule of tincture” (described as “a design philosophy”) is the convention “metal should not be put on metal, nor colour on colour”.  There appears to be no historical basis for the emergence of this rule in the early fifteenth century and the favored modern explanation is that imposing it simply made it easier for the craftsmen of the era, it being technically challenging to inlay metals in metals, the practical point being a high wastage rate of expensive materials (the client paying only for the finished product).  However, the rule took hold rather in the manner the strictures in some religions (such as prohibitions on the consumption of shellfish or pig products) began as public health measures in the pre-refrigeration age endured to become orthodox articles of faith.  Centuries later, although the application of the “rule” began to be relaxed, such was the enduring influence that artisans' guilds formally codified a list of “exemptions” from the rule.

Meaning shift

The historic meaning of tincture (a synonym for dye or pigment) is now entirely obsolete; a tincture is now a subtle shade, tint or variation of an original colour or a smattering of another.  It can be applied to any field vaguely analogous such as tastes or aromas and can be used pejoratively to suggest someone’s knowledge of something might be less than advertised.  It has also found a niche is recipes printed in up-market publications as a word to use instead of "hint".

Lindsay Lohan tinctures: copper and auburn variations of red.

The Dendrobates tinctorius “Giant Orange” (the common name the "Dyeing Poison Dart Frog" (based on the early belief natives used brightly colored frogs to dye feathers & fabrics)).  Described by retailers as a “great beginner frog” (the reason for that presumably understood by collectors) and “best kept in pairs”, the RRP (recommended retail price) is US$59.99.

The adjective tinctorious dates from the late eighteenth century and appears first to have been used of colorful plants.  Even in horticulture it has become rare but an echo survives in the Dendrobates Tinctorius, a frog much prized by collectors and photographers for its striking colors and patterns.  Unsurprisingly referred to usually as "tincs" (the standard abbreviation of "tincture") Dendrobates Tinctorius is one of the largest species of poison dart frogs, although in global terms still hardly large, the largest some 2 inches (50 mm) length. They are native to the rainforests of South America and appear in dramatic color combinations including hues of blue, black, yellow and orange.  They can safely be kept by hobbyists because in captivity they're not poisonous, their toxicity in the wild by virtue of their preferred diet of small invertebrates, not consumed in a captive environment.  Prices of adults in the most desired color mixes can exceed US$120.
