The "Atlantic" anti-submarine scheme is dark gull gray over white. An interim scheme before the final Atlantic scheme consisted of dark gull gray tops, light gull gray sides, white bottoms. Photos of aircraft in this first scheme are rare, though. Most received the later scheme. You can apply it to Helldivers, Dauntlesses, Avengers, Wildcats, PBYs, PBMs and PB4Y-1s. It did not apply to Hellcats and Corsairs, but wouldn't they have looked sharp?
