Thayer did carry out an experiment on dazzle camouflage, but it failed to show any reliable advantage over plain paintwork. [35] The American data were analysed by Harold Van Buskirk in 1919. About 1,256 ships were painted in dazzle between 1 March 1918 and the end of the war on 11 November that year.
USN measure 12 was a graded system with sea blue low on the hull below the first continuous deck, with ocean gray above that. The top of the masts were painted haze gray. [36] This measure was modified with ocean gray above navy blue low on the hull below the first continuous deck (painted parallel to the waterline rather than the main deck).
Where transparency cannot be achieved, it can be imitated effectively by silvering to make an animal's body highly reflective. At medium depths at sea, light comes from above, so a mirror oriented vertically makes animals such as fish invisible from the side. Most fish in the upper ocean such as sardine and herring are camouflaged by silvering ...
Thayer's 1902 patent application. He failed to convince the US Navy. The English zoologist Edward Bagnall Poulton, author of The Colours of Animals (1890) discovered the countershading of various insects, including the pupa or chrysalis of the purple emperor butterfly, Apatura iris, [2] the caterpillar larvae of the brimstone moth, Opisthograptis luteolata [a] and of the peppered moth, Biston ...

With the likelihood of the United States entering the war, and after experiments with various paint schemes conducted in association with the 1940 Fleet Problem (exercise), the Bureau of Ships (BuShips) directed in January 1941 that the peacetime color of overall #5 Standard Navy Gray, a light gloss shade with a linseed oil base, be replaced with matte Dark Gray, #5-D, a new paint formulation ...
Cott's method is to provide a large number of examples, illustrated with his own drawings or photographs, showing animals from different groups including fish, reptiles, birds and insects, especially butterflies. The examples are chosen to illustrate specific adaptations. For example, the fish Chaetodon capistratus is described as follows: [P 2]
