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
Military camouflage patterns of the new nations changed, coming to resemble the camouflage patterns used by the armies of their neighbours. The authors note that military camouflage resembles animal coloration in having multiple simultaneous functions. Seasons may play a role in some regions. A dramatic change in colour and texture is created by seasonal snowy conditions in northern latitudes, necessitating repainting of vehicles and separate snow oversuits. The Eastern and northern European countries have a tradition for separate winter uniforms rather than oversuits. During the Second World War, the Waffen-SS went a step further, developing reversible uniforms with separate schemes for summer
