Well the USN had a number for all the colors, and patterns they used. If you can find the number then it would be pretty easy. Actually modelling websites have alot of info on the colors used by USN ships, example:
http://www.steelnavy.com/usnchips.htm
The book discussed on that site about US Camo patterns called SHIPS-2, I have found a link to the 1942 revision 2 if that is of any use:

Hope that helps
