The 31/3D drawing for the Evarts
class destroyer escorts dated January 25, 1944, the vertical colors were specified to be: dull black (BK), ocean gray (5-O) and haze gray (5-H), but most ships used Measure 32 colors. Note the heavy lines drawn to emphasize the borders between the ocean gray and the haze gray, which gave rise to a variation with black lines between the colors. The stern view at upper left also gave rise to other variations as some ships tried to match what was really the edge on view of the sides by painting extra panels and bands on the stern.
A Design 3D drawing was attached to the July 15, 1943, memo to PacFleet for the DD-380 Gridley class of destroyers. Design 3D was also drawn for every other class of destroyers and destroyer escorts and for most other classes of major warships including the Independence class light carriers, the Casablanca class escort carriers, Omaha class light cruisers and Cleveland class light cruisers. The battleship USS Colorado (BB-45) also used Design 3D beginning in October 1943. A handful of ships of the Livermore class of destroyers and some destroyer escorts used a mirrored version in which the port pattern appeared on the starboard and the starboard pattern was painted on the port side. I have identified this as 3D rev (reversed) even though there seem to be no USN drawings that would depict this.
