Chromatophores are cells that produce color, of which many types are pigment-containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods.

Mammals and birds, in contrast, have a class of cells called melanocytes for coloration.
