Every color an animal wears comes from just two toolkits: pigments and structure. Pigments are colored chemicals — melanin makes blacks, browns, and golds, while carotenoids from food make many reds, oranges, yellows, and pinks. Structural color is different: microscopic
Gray is what you get when melanin is spread thin — a mix of dark pigment and pale, unpigmented bands along each hair. Many “gray” mammals, like wolves and squirrels, are actually wearing hairs banded in black, white, and brown
