How does a chameleon know what color to change to?

Do chameleons change color voluntarily?

Unlike other animals that change color, such as the squid and octopus, chameleons do not modify their hues by accumulating or dispersing pigments within their skin cells, the researchers found. Instead, the lizards rely on structural changes that affect how light reflects off their skin, the researchers said.

Chameleons change colors to reflect or absorb light and temperature . When lying under the hot sun, for example, chameleons can change into a lighter color to reflect the brightness of the sun.

Can a chameleon actually change color?

In short, yes, chameleons do change color. But, as with many things, the deeper answer is a little more complicated. A chameleon’s color is changed less by a pigmentation manipulation than a structural change in the nanocrystals in their skin.

A chameleon changes its color to adjust its body temperature to that of the outside temperature. A cold chameleon will turn dark to absorb more heat, while a hot chameleon will turn lighter in shade in order to reflect the heat from its body. Also the change in color in a chameleon can indicate its mood.

Why does a chameleon change its color?
