A silhouette of the drawing for Design 7D for the Fletcher class destroyers dated August 19, 1943. The colors were not specified, but it could be used for multiple measures. Starting with the darkest color of dull black (BK), if the lightest vertical color was light gray (5-L) it would be Measure 32. If the lightest color used were ocean gray (5-O) or haze gray (5-H), then this would result in Measure 31.
A Design 7D drawing was attached to the July 15, 1943, memo to PacFleet for the DD-381 Somers class of destroyers. On August 19, 1943, it appeared for the Fletcher class destroyers. Design 7D was redrawn for the Farragut class destroyers, the Gamble class light minelayers and for the Chandler class high speed minesweepers; it was worn by, at least, USS Gamble (DM-15), USS Sicard (DM-21) and USS Hamilton (DMS-18). This design was also slightly modified and drawn for the Portland class heavy cruisers on March 21, 1944, using three colors and worn by the cruisers USS Portland (CA-33) and USS Indianapolis (CA-35) and it was worn by the battleship USS West Virginia (BB-48).
