Camouflage the peacock flounder, squid and octopus actively change their skin patterns and colours using special chromatophore cells to resemble their current background, or, as in most chameleons, for signalling. However, Smith's dwarf chameleon does use active colour change for camouflage. Each chromatophore contains pigment of only one colour. In fish and frogs, colour change is mediated by the type of chromatophores known as melanophores that contain dark pigment. A melanophore is star-shaped; it contains many small pigmented organelles which can be dispersed throughout the cell, or aggregated near its centre. When the pigmented organelles are dispersed, the cell makes a
Dazzle camouflage testing period, the Red Bull RB11 car was painted in a scheme intended to confound rival teams' ability to analyse its aerodynamics. The designer Adam Harvey has similarly proposed a form of camouflage reminiscent of dazzle for personal camouflage from face-detection technology. It attempts to block detection by facial recognition technologies such as DeepFace "by creating an 'anti-face'". It uses occlusion, covering certain facial features; transformation, altering the shape or colour of parts of the face; and a combination of the two. The Sea Shepherd Conservation Society has used dazzle patterns on its fleet since 2009. Dazzle camouflage Dazzle camouflage,
