Jon,
The Enterprise was painted in US Navy Measure 11 camouflage in 1942 through the middle of '43 when the ship returned to the US for a major overhaul.
Measure 11 called for all vertical surfaces to be painted in Sea Blue 5-S and the flight deck to be stained in a color matching Deck Blue 20-B paint. The non-wooden decks should be 20-B. The Sea Blue color is a medium blue that can photograph much lighter AND much darker in B&W than it really looked.
I used Model Master ACRYL marine paints for my Tamiya kit. They have the correct colors. I believe that the Model Master enamels list the colors too.
The blue pigments faded very quickly in the Pacific sun, the deck stain in particular. I'd have the Deck tan color ready if you plan to weather your model.
If you haven't found the USS Enterprise Association web site, www.cv6.org, give it a look. Lots of photos and a message board for modelers of the Big "E" too.
Enjoy your model,
Mike
