Dazzle camouflage, also known as Razzle Dazzle or Dazzle painting, was a camouflage paint scheme used on ships, extensively during World War I and to a lesser extent in World War II. Credited to artist Norman Wilkinson, it consisted of a complex pattern of geometric shapes in contrasting colors, interrupting and intersecting each other.
MechanismAt first glance it seems unlikely camouflage, drawing attention to the ship rather than hiding it, but this technique was developed after the Allied Navy's failure to develop effective means to disguise ships in all weather. Dazzle did not conceal the ship but made it difficult for the enemy to estimate its speed and heading. The idea was to disrupt the visual rangefinders used for naval artillery. Its purpose was confusion rather than concealment.1 An observer would find it difficult to know exactly whether the stern or the bow is in view; and it would be equally difficult to estimate whether the observed vessel is moving towards or away from the observer's position.2 The rangefinders were based on the co-incidence principle with an optical mechanism, operated by a human to compute the range. The operator adjusted the mechanism until two half-images of the target lined up in a complete picture. Dazzle was intended to make that hard because clashing patterns looked abnormal even when the two halves were aligned. This became more important when submarine periscopes included similar rangefinders. As an additional feature, the dazzle pattern usually included a false bow wave to make estimation of the ship's speed difficult. The demonstrable effectiveness of the bold Dazzle camouflage was accepted by the Admiralty, even without practical visual assessment protocols for improving performance by modifying designs and colors.3 The Dazzle camouflage strategy was adopted by other navies. This led to more scientific studies of color options which might enhance camouflage effectiveness. Broken color systems which present units so small as to be invisible as such at the distances considered are neither advantageous or detrimental. The visibility of the camouflaged vessel would depends entirely upon such scientifically measurable factors as the mean effective reflection factor, hue and saturation of the surface when considered at various distances.4 In the UK, the army introduced its Camouflage Section at the end of 1916: while at sea, the marine painter Norman Wilkinson invented the concept of “dazzle painting” — a way of using stripes and disrupted lines to confuse the enemy about the speed and dimensions of a ship.5 Wilkinson, then a lieutenant commander on Royal Navy patrol duty, implemented the precursor of "dazzle" on SS Industry; and the HMS Alsatian became the first Navy ship in August 1917. All British patterns were different, first tested on small wooden models viewed through a periscope in a studio. Most of the model designs were painted by women artists from London's Royal Academy of Arts. A foreman then scaled up their designs for the real thing. Painters, however, were not alone in the project. Creative people including sculptors, abstract artists, and set designers designed camouflage6 World War I

Dazzle's effectiveness is not certain. The British Admiralty concluded it had no effect on submarine attacks, but proved to be a morale boost for crews. It also increased the morale of people not involved in fighting; hundreds of wonderfully coloured ships in dock was nothing ever seen before or since. In a 1919 lecture, Norman Wilkinson explained:
During both World Wars, former ocean liners owned by British steamship companies like Cunard Line were re-commissioned as an integral part of the British fleet. These auxiliary vessels were re-fitted with armament and re-painted in the same manner as other fleet ships. For example, this meant that the former Canadian Pacific Steamships passenger liner, the RMS Empress of Russia, was given the "dazzle" treatment when she was converted into a troopship. World War IIAmerican naval leadership thought dazzle effective. In 1918, the U.S. Navy adopted it, as one of several techniques Dazzle continued to be used until the end of World War II. However effective the scheme was in WWI, it became less useful as rangefinders became more advanced, and, by the time it was put to use again in WWII, radar further reduced its effectiveness. However, it may still have confounded submarines. The US Navy implemented a camouflage painting program for all Tennessee-class battleships in World War II. The designs were not arbitrary, but were standardized in a process which involved a planning stage, then a review, and then fleet-wide implementation.
Art historyThe Cubists aimed to revolutionise painting — and reinvented the art of camouflage on the way.2 The art of war recognizes the values of art in war. Winston Churchill considered deception in war to be an indispensable "element of legerdemain, an original and sinister touch, which leaves the enemy puzzled as well as beaten."Latimer, Jon. (2003). Deception in War: The Art of the Bluff, the Value of Deceipt, and the Most Thrilling Episodesof Cunning in Military History, from the Trojan Horse to the Gulf War, (abstract). In 2007, the art of concealment was featured as the theme for a show at the Imperial War Museum. The evolution of Dazzle was re-examined in this context. Picasso is reported to have taken credit for the modern camouflage experiments which seemed to him a quintessentially Cubist technique.7 He is reported to have drawn the connection in a conversation with Gertrude Stein shortly after he first saw a painted cannon trundling through the streets of Paris.2 See alsoNotes
