The chameleon has several cell layers beneath its transparent skin and are the source of the chameleon’s colour change. Some of the layers contain pigments, while others just reflect light to create new colours. There are several factors that lead to the chameleon change its colour. A popular misconception is that chameleons change colour to match their environment. This isn't true. Light, temperature and emotional state commonly bring about a chameleon’s change in colour. The chameleon will most often change between green, brown and grey, which coincidently, often matches the background colours of their habitat.
