Colouring and Perfumery
See also: Saffron (color)Despite its high cost, saffron has been used as a fabric dye, particularly in China and India. It is in the long run an unstable colouring agent; the imparted vibrant orange-yellow hue quickly fades to a pale and creamy yellow. Even in minute amounts, the saffron stamens yield a luminous yellow-orange; increasing the applied saffron concentration will give fabric of increasingly rich shades of red. Clothing dyed with saffron was traditionally reserved for the noble classes, implying that saffron played a ritualised and status-keying role. It was originally responsible for the vermilion-, ochre-, and saffron-hued robes and mantles worn by Buddhist and Hindu monks. In medieval Ireland and Scotland, well-to-do monks wore a long linen undershirt known as a léine, which was traditionally dyed with saffron. In histology the hematoxylin-phloxine-saffron (HPS) stain and Movat's pentachrome stain are used as a tissue stain to make biological structures more visible under a microscope. Saffron stains collagen yellow.
There have been many attempts to replace saffron with a cheaper dye. Saffron's usual substitutes in food—turmeric and safflower, among others—yield a garishly bright yellow that could hardly be confused with that of saffron. Saffron's main colourant is the flavonoid crocin; it has been discovered in the less tediously harvested—and hence less costly—gardenia fruit. Research in China is ongoing. In Europe saffron threads were a key component of an aromatic oil known as crocinum, which comprised such motley ingredients as alkanet, dragon's blood (for colour), and wine (again for colour). Crocinum was applied as a perfume to hair. Another preparation involved mixing saffron with wine to produce a viscous yellow spray; it was copiously applied in sudoriferously sunny Roman amphitheatres—as an air freshener.

Famous quotes containing the words colouring and/or perfumery:
“The innocent brightness of a new-born Day
Is lovely yet;
The Clouds that gather round the setting sun
Do take a sober colouring from an eye
That hath kept watch oer mans mortality;”
—William Wordsworth (17701850)
“I see that every man that went in had his pockets bulging, or something muffled up under his coatand I see it warnt no perfumery either, not by a long sight. I smelt sickly eggs by the barrel, and rotten cabbages, and such things; and if I know the signs of a dead cat being around, and I bet I do, there was sixty-four of them went in. I shoved in there for a minute, but it was too various for me, I couldnt stand it.”
—Mark Twain [Samuel Langhorne Clemens] (18351910)
