A chameleon will change color when it senses danger. This remarkable member of family can change color to match its background or, at least to become almost unrecognizable.
The ranges of color and patterns of the various species differ widely, but most chameleons can become yellow or cream, green or dark brown. They can also adapt spots either dark or light depending on the color of the ground.
Apart from its response to danger, the chameleon will change color according to the light and temperature. This mechanism is controlled from the nervous system and involves the dispersion or concentration of color pigments in the creature’s skin.
