I meant to say "xanthophores" can also be responsible for both yellows and reds, not "erythrophores"..LOL!

Xanthophores

These chromatophores produce red and yellow pigments known as pteridines. These may vary in color from pure yellow to pure red, as well as intermediate shades. Xanthophores possessing a predominantly red coloration are referred to as erythrophores.

Xanthophores also retain yellow to reddish pigments contained in the diet in the form of carotenoids. Carotenoid retention continues throughout life, and intensity of pigmentation varies based on the quantity and types of carotenoids contained in the diet. Additionally, the animals' genetic predisposition towards and ability to store carotenoids will affect appearance.
