Some of the layers contain pigments, while others just reflect light to create new colors. Several factors contribute to the color change. A popular misconception is that chameleons change color to match their environment. This isn't true. Light, temperature, and emotional state commonly bring about a chameleon's change in color. The chameleon will most often change between green, brown and gray, which coincidently, often matches the background colors of their habitat.
