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
Disruptive Pattern Camouflage Uniform grey, sand, olive-green and red-brown. The new variant was designed to overcome issues associated with operating in and around the "green belt" areas of Afghanistan (particularly in corn fields) where the DPDU was too light in colour but where the DPCU was too green for open areas. Trials however, showed that in most areas the original DPCU performed more effectively than the new Midpoint camouflage and it was not adopted. One criticism was that the new camouflage used colours that were still too biased towards desert operations. Australian special forces operating in Afghanistan have been seen wearing Crye's Multicam camouflage.
