Back in the 1980s I did some research while scratch building the USS Swanee. Amongst other material was that photo of Santee. It appears to have originated when taken for an article in National Geographic. She had been operating in the North Atlantic from early 1942. There is a picture of her in NAVSOURCE taken in September, when the measure 17 scheme was fairly fresh. The color picture is dated as October 18 and came from the national archives. The color film used at the time had a heavy skew into the blue range and tends to make the actual color difficult to ascertain. By December, it was gone. A fresh coat of paint exposed to north Atlantic weather lasted only a couple of months, at best, between the pounding of the sea and direct sunlight the paint chipped and faded rapidly. Constant spot painting, undercoated with chrome yellow to prevent corrosion, was always being done. That's what those yellow patches were. Measure 17 was roughly equivalent to the Royal Navy's Western Approaches Scheme and was lighter in hue than regular Navy colors. Essentially it was an attempt to come close to the Royal Navy, but using USN stocks. USNavy colors at that time were based upon the Munsell book of color. The measures were established upon, white, ultramarine blue, and black colors. Navy blue, Ocean gray, Haze gray, Deck blue, were all proportionate mixtures of these pigments. The principal difference between one color and another was the amount of white added to the others. There was no such thing as a neutral gray until 1944 when modern alkyd paints made it possible. There was no correlation to FS-595 since that came along post war in 1956. The Snyder and Short color chips are a very good match to actual USN color chips, but they would represent fresh paint and not anything which had begun to weather. The tinting agent a mixture of ultramarine blue and black is the source of many paint problems. Initially thought to be a stable color, it was far from that in actual use. The blue tended to break down rapidly when exposed to the elements and faded quickly. Because of that ultramarine blue base, these colors are very difficult if not impossible to match with the colors available in computer inks, and most commercial paints. To obtain a really accurate match one can get close using Humbrol Napoleonic blue in mixtures to get that ultramarine hue. The photographs of USS Chicopee available on NAVSOURCE show at least five different colors ranging from white to Ocean gray. The disruptive scheme is fresh and dated as August 16, 1942. It was gone by December. As for decks, metal surfaces were painted and teak surfaces were stained. Stain soaks deeply into wood fibers and was not really removable. Consequently wood decks of prewar ships, especially carriers, had that mahogany undertone even after blue stain had been applied. Aircraft carrier decks are quite another topic and do not correlate with the decks of other warships. The measure 17 scheme was evidently instituted to defeat angle of approach evaluation, particularly by u-boats in the ETO. It did not help much in the Pacific. USN Ships 2 painting instructions gives illustrations, but not much of a discussion. Although splinter schemes appeared until after the war, naval thinking after early 1943 turned to visibility as opposed to disruption and Measure 17 passed from the scene. The primary attention was on protection against aircraft as opposed to submarine attack. Hope this is useful.
