1/700 presents some challanges due to 'scale effect." At 12" from the kit, you are a scale 700 feet away, which washes colors, and color distinctions away--as any photo from that distance will readily show.
At the same time, we are modelers, we are up close and personal with our builds, our exstence with them is far more direct and "close up" than for a casual vewer.
For 2¢, what I have done is to select the blue color for the deck, and a the different color for the wooden flight deck, and the 3rd color for the hull sides.
The deck blue is a very deep blue, if less dark than the "Navy Blue" used on aircraft. Feldblau, the Luftwaffe uniform color can more n handy here, as can some of the "bluish" panzergrau. (Both of those beng slightly better for the earlier overall "Sea"blue rather than the later "Navy" blue.)
Oh, and since we are on this, note that the hangar deck, and those places sheltered by the flight deck will be in "deck" gray (and there's a fist fight in deciding what that is, and I'm disinclined to joint it).
Perversely, despite the instructions, Big E seems to have never sailed wth white counter-shadng point. Such is life aroundcapital ships.
f you'd like a bit more depth on ths business, wiki has a reasonably good artcle under "WWII USN Camoflage" with photos and some (small) color samples.
