How do animals change color?

the science of chromatophores

Animals like cuttlefish and chameleons are able to quickly change color in-order to blend in with their surroundings. They can do this due to a special type of cell called a chromatophore. Chromatophores work by moving vesicles that contain different color pigments into different forms by contracting and expanding them, so a different color comes to the “surface” when moved, giving the animal a different color. This can either be controlled by the animals nerves or happen hormonally.
