I've been sporadically working on updating my Corsair template so I can redo my skins with bump and spec maps, and I ran across some info anyone working on USN/MC Corsair skins might find useful:
Seems that, at least on Marine Corsairs, there were actually FOUR colors used in the "tricolor" scheme. The wing tops were actually painted a slightly different color from the fuselage:
Upper Wing Surfaces - Semi-gloss Sea Blue (RGB: 53, 63, 69)
Upper Fuselage - Flat Sea Blue (RGB: 69, 74, 78)
Another useful color is Yellow Zinc Chromate (RGB: 227, 210, 8). This is the primer that Vought applied on all of the Corsair's metal parts prior to painting, and it was also used to protect the interior of the wheel wells from corrosion (Vought didn't paint the wheel well interiors and the interiors of the landing gear doors. These ought to be done in chromate). You would also use this color for the interior of the engine cowling.
From research I did while working on plastic models, this is also the color that should be used on most of the F4U-1/A/D/C cockpit interior, specifically the rear and forward bulkheads, control stick, seat, rudder pedals, and the rest of the cockpit tub below the side consoles. From what I've been able to find, the only part of these models' cockpit that was (typically) painted Interior Green would have been the sidewalls above the consoles. Obviously, this can only be applied to exterior skins for right now, unless providing cockpit interior skins would ever be allowed...
