Why does the chameleon change colours?

Animals use the technique of camouflage to escape predators. By changing colours the chameleon is camouflaging itself. This is made possible thanks to special red, black and yellow cells in its skin. The chameleon changes colours by changing the size and shape of these cells so that it matches different backgrounds like a tree branch or a wall or the earth.
