Camouflage there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of actively changing their skin pattern and colours, whether for camouflage or for signalling. It is possible that some plants use camouflage to evade being eaten by herbivores. Military camouflage was spurred by the increasing range and accuracy of firearms in the 19th century. In particular the replacement of the inaccurate musket with the rifle made
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
