What are pigments?
In nature, fish such as salmon get their pink colour from eating crustaceans.. Carotenoids, the most common naturally occurring pigments, are given to farmed fish to provide Vitamin A, function as antioxidants, and enhance the animals’ immune system. Carotenoids also give farmed fish, such as salmon and Arctic Char, their pink colour.
• Pigments are dry, powdery materials which happen to possess color. They come from many sources and they vary greatly in their characteristics. • Pigments have little or no affinity for the surface onto which they are applied. The use of a binder (e.g. gum arabic, oil) is required to unite the pigment with the painting surface, whether it be paper, canvas, plaster or metal. • Pigments are particulate materials which do not dissolve, but remain dispersed or suspended when mixed with a vehicle. • Pigments are either organic (containing carbon) or inorganic (without carbon). • Some pigments come from natural sources. Earth colors, such as umbers and siennas are really natural earth. Other pigments, such as the cadmium colors, are manufactured.
