I think the color would be up to you. That was before the USN standardized it's colors. While it might be a bit more expensive, you could simple create a color comparison chart and pick whichever seems to be correct to you. As the photos on NavSource show, the paint under goes changes due to sun exposure, UV, and freshly painted will appear significantly different than aged sea worn paint. I do remember a wonderful book that explained adding grey or white to a color to create the hazy effect that the atmosphere creates, causing colors to change.Good luck, and remember, if someone says something about your effort, tell them to prove their facts, it's not up to you.
