Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other biological sources such as fungi. [1] Archaeologists have found evidence of textile dyeing dating back to the Neolithic period.
Natural insect dyes such as Cochineal and kermes and plant-based dyes such as woad, indigo and madder were important elements of the economies of Asia and Europe until the discovery of man-made synthetic dyes in the mid-19th century. The first synthetic dye was William Perkin's mauveine in 1856, derived from coal tar.
Indigo is a natural dye extracted from the leaves of some plants of the Indigofera genus, in particular Indigofera tinctoria. Dye-bearing Indigofera plants were commonly grown and used throughout the world, particularly in Asia, with the production of indigo dyestuff economically important due to the historical rarity of other blue dyestuffs.

Many of the dyes are made from lichens, the useful ones for this purpose being known as crottle.. The process employed is to wash the thread thoroughly in urine long kept ("fual"), rinse and wash in pure water, then put into the boiling pot of dye which is kept boiling hot on the fire.
Scarce dyestuffs that produced brilliant and permanent colors such as the natural invertebrate dyes Tyrian purple and crimson kermes were highly prized luxury items in the ancient and medieval world. Plant-based dyes such as woad, indigo, saffron, and madder were important trade goods in
A rare, 3,600-year-old purple dye workshop uncovered on a Greek island sheds light on the mysteries surrounding the once revered hue, according to archaeologists.

Natural rose madder supplied half the world with red, until 1868, when its alizarin component became the first natural dye to be synthetically duplicated by Carl Gräbe and Carl Liebermann. Advances in the understanding of chemistry, such as chemical structures, chemical formulas, and elemental formulas, aided these Berlin-based scientists in ...
