I’m a member of a Living History Crew on the USS Alabama BB-60. If you have any questions, I may be able to answer them.
There was a thread I found on modelwarships.com that discussed Vallejo paints and WW2 naval colors. It included a link to a document on mixes for the various colors. Here’s the link to the document, a .pdf you can download. It may be of interest…

The Deck Blue refers to the WW2 time frame. The current deck is, as you saw, Unpainted, but the Ship still has the WW2 camo scheme otherwise.
It’s Your Model so Pick WW2 or 2020 or anything in between. As was said before, there are plenty of color photos of the Museum ship available.
This is a really nice kit. If you go for the WW2 “version”, and want to delve into “Rivet counting”, there is plenty of help here.

Museum ships are not accurate. They operate on very limited budgets. Their primary purpose is to provide a pleasant visitor experience and showcase some history, but they are maintained in most cases by volunteers and those folks beg, borrow and find whatever they can that’s useful.
Most if not all were mothballed at one point or another, when a lot of equipment was removed.
