Camouflage – be it natural or manmade – is an attempt by an individual person or animal to hide itself in its surrounding environment. This includes things like a tiger’s stripes, a soldier’s uniform or a chameleon’s color-changing ability. The word camouflage comes from the French word 'camoufler' meaning 'to disguise'. All camouflage basically boils down to two forms: disruptive camouflage and blending camouflage.
Disruptive camouflage is produced by breaking up and thereby concealing the structural lines of the object that is hiding. An exact color match with the environment is much less important than the patterning of the regions of color themselves. Disruptive patterns counter natural perceptual models.
Blending camouflage is a more obvious approach. The camouflaged object is shielded by matching the color, texture, shape, or pattern of other objects in the environment. In nature the copied objects tend to be non-edible and non-threatening. This camouflage is also called high-similarity camouflage or figure-ground blending. It should be noted that certain harmless species have reversed the concept by matching an highly visible species, that is also highly toxic.
