Normal Wilkinson invented a style of camouflage, consisting of what?
Dazzle camouflage Dazzle camouflage, also known as razzle dazzle (in the U.S.) or dazzle painting, was a family of ship camouflage used extensively in World War I, and to a lesser extent in World War II and afterwards. Credited to the British marine artist Norman Wilkinson, though with a rejected prior claim by the zoologist John Graham Kerr, it consisted of complex patterns of geometric shapes in contrasting colours, interrupting and intersecting each other.
Blackout (wartime) A blackout during war, or in preparation for an expected war, is the practice of collectively minimizing outdoor light, including upwardly directed (or reflected) light. This was done in the 20th century to prevent crews of enemy aircraft from being able to identify their targets by sight, for example during the London Blitz of 1940. In coastal regions a shore-side blackout of city lights also helped protect ships from being seen in silhouette against the shore by enemy submarines farther out at sea.
