Their skin contains a lattice of guanine crystals which mainly reflect blue light. They also have yellow pigments in their skin so naturally they look green.

They can excite this crystal lattice making the crystals move to be further apart. his causes them to reflect longer wavelengths and turn different colours.

A chameleons skin is transparent at its outermost layer, beneath this are multiple layers of cells called chromatophores. These chromatophores have little sacs filled with different pigments and are responsible for different colors.

As for how it uses them, its nervous system activates them so that different colors are shown due to different stimuli. A chameleon that’s excited for example will use its red colors while a calm one will turn green and maybe a bit of blue.
