USS Ammen (DD-527) in a October 1944 photo off Leyte wearing camouflage Design 24D using what appears at first to be dull black and a color that is darker than light gray. However, the use of black for the hull number suggests light gray, so a dark photo exposure may be causing the light gray to show darker. Thus this is Measure 32 and not 31 as reported in other sources. Photo source: NARA 80-G-374964.
