Camouflage

Camouflage is a set of methods of concealment that allows otherwise visible animals, military vehicles, or other objects to remain unnoticed by blending with their environment or by resembling something else. Examples include a leopard's spotted coat, the battledress of a modern soldier and a leaf-mimic butterfly. Camouflage is a form of visual deception; the term probably comes from camouflet, a French term meaning smoke blown in someone's face as a practical joke.
