    Indigo dye is an organic compound with a distinctive blue color (see indigo). Historically, indigo was a natural dye extracted from plants, and this process was important economically because blue dyes were once rare. A large percentage of indigo dye produced today – several thousand tons each year – is synthetic. It is the blue often associated with blue jeans.

Disperse Red 9 is used in some older red and violet-red colored smoke formulations. It is used in the M18 colored smoke grenade and also often in dye packs. Its properties can be improved by coating the dye particles with an inert material, e.g. an epoxy resin.

    Dyes refer to a class of organic compounds that can give other substances a bright and firm color. Since the dyes used today are all synthetic, they are also called synthetic dyes. The color of the dye itself does not represent its color on the fabric. "Dye" on Echemi mainly supplies raw materials for dyes.
