According to studies held by Professor Milinkovitch of the University of Geneva, only adult males can change color.
Much like peacocks, male chameleons use color change to seduce a female. This change also serves to scare away other rival males who would dare to approach the coveted female. For a long time, researchers thought that the chameleon sought to camouflage itself from its predators by merging into its environment.
Hiding is, therefore, a secondary reason. Researchers believe chameleons are expressing their mood. I am relaxed, I am angry, I am excited.

South Africa's Smith's dwarf chameleon has two deadly enemies: a shrike that impales the lizard on thorns before eating it and a venomous snake called a boomslang.
In a University of Melbourne study involving 16 chameleons, researchers found that the lizards consistently color-matched themselves more precisely to their backgrounds when presented with a model of the shrike, which has excellent eyesight, than the snake, which doesn't. When a snake goes after a chameleon, he usually approaches from below and moves towards the light, so the chameleon hides in plain sight by making himself paler, the researchers concluded.
But looking down from above, the shrike would spot any chameleon that didn't blend in perfectly with his background. Scientists at the University of Cambridge call chameleons "just phenomenal," but say it's a "myth" that they change color to camouflage themselves. Their skin is covered with several layers of very special cells called chromatophores that respond to chemicals from the nervous system and bloodstream.
