A '''dye''' is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an [[Water|aqueous]] solution, and may require a [http://en.wikipedia.org/wiki/Mordant mordant] to improve the fastness of the dye on the fiber.

Both dyes and pigments [[appear]] to be [[colored]] because they absorb some wavelengths of [[light]] more than others. In [[contrast]] with a dye, a [http://en.wikipedia.org/wiki/Pigment pigment] generally is insoluble, and has no affinity for the substrate. Some dyes can be [http://en.wikipedia.org/wiki/Precipitation_(chemistry) precipitated] with an inert salt to produce a [http://en.wikipedia.org/wiki/Lake_pigment lake pigment], and based on the salt used they could be aluminum lake, calcium lake or barium lake pigments.

Dyed [http://en.wikipedia.org/wiki/Flax flax] fibers have been found in the [http://en.wikipedia.org/wiki/Georgia_(country) Republic of Georgia] dated back in a prehistoric cave to 36,000 BP. [[Archaeological]] [[evidence]] shows that, particularly in India and Phoenicia, dyeing has been widely carried out for over 5000 years. The dyes were obtained from [[animal]], [[vegetable]] or [[mineral]] [[origin]], with no or very little processing. By far the greatest [[source]] of dyes has been from the [http://en.wikipedia.org/wiki/Plant_kingdom plant kingdom], notably roots, berries, bark, leaves and wood, but only a few have ever been used on a commercial scale.[http://en.wikipedia.org/wiki/Dye]
