802 Sqn it is! Well done! I thought that would be a tough one...
It is in fact an American interpretation of the Tropical Sea Scheme, using (apparently) AN Blue (Flag Colour) 24, Sea Green 28 and Light Blue 27. These colours are based on an analysis in "On Target Special No2 Britain Alone" of Martlet MkI AL246, which still has its original factory paintwork beneath subsequent layers of British paint.
802 may still have had aircraft in these colours when they embarked on Audacity in September 1941... Although it looks fairly unlikely, as by May 1941, the makers were getting the colours closer to the Temperate scheme, using two shades of green in fact. That implies that somebody in the food chain got out of his chair to solve the problem. 804 Sqn received their Martlets painted this way in September 1940, and repainted them in the standard Temperate Sea Scheme immediately. 802 received the next batch in November 1940, and apparently did not. Anybody's guess.
