Out of curiousity, where did you find that info?
I can't recall where I first read about "dark sea blue," but I it was a standard "dark blue" color for naval aircraft.
If you do a Google search for the F4F Wildcat, you will find that it was painted in dozens of different color schemes. Dark blue was just one of many. There were some two- and three-color designs, some in blue, others in gray. There is even a three-color scheme of silver-gray fuselage, yellow wings, and black tail.
There is lots of available information if you dig around on the Internet.
