Chromophores: Cells responsible for holding pigment.
Xanthophores: produce yellow pigment.
Erythrophores: produce red pigment.
Melanophores: produce black pigment (melanin).
Iridophores: Hold no color pigment but, hold highly reflective non-motile purine crystals that yield silver irridescent reflections.
Leucophores: Hold no color pigment. Motile purine crystals produce white pigment.
