What:

"Until now, we thought chameleons changed colour by moving packets of melanin – the same pigment that gives our skin, hair and eyes their colour – around on their skin. Melanin is like a stage curtain that the chameleon can pull across to conceal brightly coloured skin cells filled with red, blue or yellow pigments. Changing which coloured cells are "on stage" determines the chameleon's colour."
