Chameleons’ colours reflect their mood

Chameleons are known as masters of camouflage. This common knowledge assumes that chameleons change their colours to blend in the environment. However, recent scientific evidence demonstrates that it is quite the opposite. At rest, chameleons are greenish-brownish and naturally blend in the lush environment. Chameleons change their colours when they encounter other chameleons. During the contest, they display shades of yellow, orange, green and turquoise. The most colourful chameleon wins before the fight even had time to begin. More on the story read here or watch a YouTube video here. The scientific article can be accessed here.
