Pigment

Pigment is a finely powdered, highly colored substance used to give color to another material. It does so when mixed with the material or applied over the material's surface in a thin layer. Pigments mixed with a liquid do not dissolve, but remain suspended in the liquid. Colored substances that dissolve and give their color effects by staining are called dyes. Manufacturers use pigments in such products as ink, paint, and plastics. The same types of pigment are used in all products. Some pigments are produced chemically. Others come from natural sources. See also Color.
