Mr. Woodward, in Woodward and Burnett's "Treatise on Heraldry," alludes to various tinctures amongst Continental arms which he has come across.
"Besides the metals, tinctures, and furs which have been already described, other tinctures are occasionally found in the Heraldry of Continental nations; but are comparatively of such rarity as that they may be counted among the curiosities of blazon, which would require a separate volume. That of which I have collected instances is Cendrée, or ash colour, which is borne by (among others) the Bavarian family of Ashua, as its armes parlantes: Cendrée, a mount of three coupeaux in base or.
"Brunâtre, a brown colour, is even more rare as a tincture of the field; the Mieroszewsky in Silesia bear, 'de Brunâtre, A cross patée argent supporting a raven rising sable, and holding in its beak a horseshoe proper, its points towards the chief."
"Bleu-céleste, or bleu du ciel, appears occasionally, apart from what we may term 'landscape coats.' That it differs from, and is a much lighter colour than, azure is shown by the following example. The Florentine Cinti (now Cini) bear a coat which would be numbered among the armes fausses, or à enquérir: Per pale azure and bleu-céleste, an estoile counterchanged."
"Amaranth or columbine is the field of a coat (of which the blazon is too lengthy for insertion in this place) which was granted to a Bohemian knight in 1701."
Carnation is the French term for the colour of naked flesh, and is often employed in the blazonry of that country.
Perhaps mention should here be made of the English term "proper." Anything, alive or otherwise, which is depicted in its natural colours is termed "proper," and it should be depicted in its really correct tones or tints, without any attempt to assimilate these with any heraldic tincture. It will not be found in the very ancient coats of arms, and its use is not to be encouraged. When a natural animal is found existing in various colours it is usual to so describe it, for the term "proper" alone would leave uncertainty. For instance, the crest of the Lane family, which was granted to commemorate the ride of King Charles II. behind Mistress Jane Lane as her servant, in his perilous escape to the coast after the disastrous Battle of Worcester, is blazoned "a strawberry roan horse, couped at the flanks proper, bridled sable, and holding between the feet an Imperial crown also proper." Lord Cowper's supporters were, on either side of the escutcheon, "a light dun horse proper, with a large blaze down the face, the mane close shorn except a tuft on the withers, a black list down the back, a bob tail, and the near fore-foot and both hind feet white." Another instance that might be quoted are the supporters of Lord Newlands, which are: "On either side a dapple-grey horse proper, gorged with a riband and suspended therefrom an escutcheon gules, charged with three bezants in chevron." The crest of the family of Bewes, of St. Neots, Cornwall, is: "On a chapeau gules, turned up ermine, a pegasus rearing on his hind legs of a bay colour, the mane and tail sable, winged or, and holding in the mouth a sprig of laurel proper."
There are and were always many occasions in which it was desired to represent armorial bearings in black and white, or where from the nature of the handicraft it was impossible to make use of actual colour. But it should always be pointedly remembered that unless the right colours of the arms could be used the tinctures were entirely ignored in all matters of handicraft until the seventeenth century. Various schemes of hatchings, however, were adopted for the purpose of indicating the real heraldic colours when arms were represented and the real colours could not be employed, the earliest being that of Francquart in Belgium, circa 1623. Woodward says this was succeeded by the systems of Butkens, 1626; Petra Sancta, 1638; Lobkowitz, 1639; Gelenius; and De Rouck, 1645; but all these systems differed from each other, and were for a time the cause of confusion and not of order. Eventually, however, the system of Petra Sancta (the author of Tesseræ Gentilitia) superseded all the others, and has remained in use up to the present time.
