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
Aircraft camouflage aircraft nearly invisible from most angles, however the sun reflecting off it defeated it even before its lack of durability did. When the Germans fielded the Albatros D.III sesquiplane, its similarity from a distance caused them to be confused for Nieuports, both of which used the same combination of colours to match the terrain they were operating over. Additionally, the Nieuports lacked overwing roundels and the German crosses were not always easy to identify. The solution the Germans came up with was to replace the red-brown with purple, which from a distance still worked well as a camouflage colour, but
