1 When we think about chameleons, the first thing that comes to mind is probably their skill in camouflage. Indeed, it is widely believed that chameleons can change their colors to fit the environment they are in. Yet, if we put this theory to the test, we would be disappointed. It turns out that chameleons do not adjust their colors to blend in with their surroundings. Rather, lights, temperatures, and their emotions are the three triggers that cause chameleons to change their color.
2 For example, when a chameleon feels cold and wants to warm up, it becomes darker. If it is in a good mood, it turns lighter. The secret behind its color changes lies in its skin.
3 Chameleons have four layers of skin. From the outermost to the innermost, the four layers are the epidermis, the chromatophore, the melanophore, and the nether. The protective epidermis layer is transparent. The chromatophore layer creates yellow and red. The melanophore layer's dark pigment (melanin) creates brown, black, and blue. The nether layer reflects white. Through their nervous system, chameleons expand or contract these pigment cells to develop the various colors and patterns that we see on the outside.
