what color for Ju 87 operating mostly over the sea

i kinda asked this question before, but mybe not in the right way. would a german plane that operated mostly by the sea use gray colors? i want to mod a ju 87b into a ju87c for a forced prospective with the aircraft carrier Graf zeppelin. was gray a color used for operations by the sea and green for inland? or did it matter? any web sites on this kind of detail would be helpfull.

Here are some sights I found, the one shows the green top. Being that no actual Ju 87C were actually completed, you could probably take some artistic license on the final color scheme:http://www.german-navy.de/kriegsmarine/aviation/carrierbased/ju87/

You get to make it up, since there were no carrier-based naval Stukas.

In the real world, I don’t think I’ve ever seen a Stuka that wasn’t in standard Luftwaffe green camo, prewar gree/brown/gray, or a desert scheme.

thanks, i guess its really up to me on what color
