The mechanisms for colour production in animals include pigments , chromatophores , structural coloration , and bioluminescence .

According to Charles Darwin 's 1859 theory of natural selection ,  features such as coloration evolved by providing individual animals with a reproductive advantage. For example, individuals with slightly better camouflage than others of the same species would, on average, leave more offspring.  There are several separate reasons why animal coloration may evolve: Camouflage , enabling an animal to remain hidden from view Signalling to other animals, of the same or different species, including: Advertising , signalling services such as cleaning to animals of other species Sexual selection , signalling sexual status to other members of the same species...
