I didn't use the profile color, Ramsey.  I read that these Kittyhawks were delivered and saw immediate combat, leaving only them in the original light blue color.  Not sure if this is correct, but I went to two separate color palette sites and found the USAAC light blue  (R9 G143 B152, Hex:598F98).  Then I played with the saturation and made it a tad more grey.
