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
Snow camouflage camouflage was not limited to paint: tracks left in the snow were to be obliterated, vehicles parked in cover, headlights covered with white fabric, shelters constructed, or else vehicles covered with white fabric, or dark fabric scattered with snow. Later in the 20th century, as disruptively patterned uniforms became widespread, winter variants of patterns such as "Flecktarn" were developed, the background colour (such as green) being replaced with white to form a "Schneetarn" (snow camouflage pattern). Aircraft deployed in winter have sometimes been snow camouflaged, as with Sepecat Jaguars on exercise in Norway. Snow camouflage is manufactured commercially for use
