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 set designers designed camouflage. Wilkinson's Dazzle camouflage was accepted by the Admiralty, even without practical visual assessment protocols for improving performance by modifying designs and colours. The dazzle camouflage strategy was adopted by other navies. This led to more scientific studies of colour options which might enhance camouflage effectiveness. After the war, starting on 27 October 1919, an Admiralty committee met to determine who had priority for the invention of dazzle. Kerr was asked whether he thought Wilkinson had personally benefited from anything he Kerr had written. Kerr avoided the question, implying that he had not, and said "I make
