A bit of history, based on what I've found in the Archives. By 1944, stocks of Ultramarine blue pigment were getting short and expensive, and the Navy started a program to decrease its use. They had learned by that time that it wasn't the color that mattered in camouflage as much as tone - light against dark will stand out regardless of color, and vice versa. So, it was decided to reformulate and go with neutral paints.
I don't have all of the documentation yet, but the
February 1945 instructions for Carriers, Cruisers, Destroyers, and Destroyer Escorts references a late November document in Paragraph 5 that indicates that they were working on changing formulas at least three months in advance of the actual order for fleets to begin using the new colors. We had thought that this was about when the new colors started appearing, but recent finds indicate that the "official" paint manufacturing yards at Mare Island and Norfolk had switched to production of the new paints by the end of December, 1944, at least as far as
this memo to a private paint manufacturing company indicates. I've been wanting to try and track the "movement" of neutral paints throughout the fleet so we could come up with some rough rules for which ships and when, etc., but I don't know how possible that will be.
