Skins: Camouflage
Colour change in chameleons has functions in social signaling and in reactions to temperature and other conditions, as well as in camouflage. The relative importance of these functions varies with the circumstances, as well as the species. Color change signals a chameleon's physiological condition and intentions to other chameleons. Chameleons tend to show darker colors when angered, or attempting to scare or intimidate others, while males show lighter, multicolored patterns when courting females.
Many creatures have developed their own natural camouflage for both hunting and escaping predators.
A ghillie suit, also known as a yowie suit, or camo tent, is a type of camouflage clothing designed to resemble heavy foliage. Typically, it is a net or cloth garment covered in loose strips of burlap, cloth or twine, sometimes made to look like leaves and twigs, and optionally augmented with scraps of foliage from the area.
Liu Bolin, a Chinese artist, created pieces of work where he would paint himself or volunteers to look like their background creating a camouflage effect where they would almost completely disappear into their background.
