I would like to know before WWII December 6th what was the color of the USS Arizona as well as after December 7th?
The short answer is that there is not one that everyone agrees with. I wrote what I consider my best attempt with what we know an posted it here back in 2011. Not much has changed. That's not to say that there haven't been efforts; we're been trying new areas in the records to look for things. Some of the records that have added to what we know in general about the Pacific Fleet, for example, were found in records of the Atlantic Fleet.
There have been a lot of busts - paint storage and distribution was handled by "Base Force" (as opposed to Battle Force and Scout Force) and while NARA has records for base force, the finding aid on site shows that there were records that existed that might have helped that were not turned over.
There is no magic footage or document that proves it one way or the other, and a lot of people have got themselves worked up at times over opinions. My opinion is that I doubt the sailors who died that day cared what color the paint that was combusting with them was and we should keep them in mind when responding to each other.
Because of the pandemic and other circumstance I haven't been able to make it to the archives for almost four years, so it's been a while since I've been able to say that we have anything new in the debate.
Conventional wisdom is Measure 1 in 5D and 5L. Proponents of the conventional wisdom have denied some aberrations and had to walk back a few claims, but there is no denying Arizona was in standard Measure 1 from probably early June into the fall of 1941. You can build a Measure 1 Arizona and have a model that is known accurate for a significant part of the year.
December 7th is a matter of opinion, and people have a right to theirs. I see no harm in saying "we don't know for sure yet" and leaving the matter somewhat in the air. If you spend time to build a model of their ship, regardless of what scheme you choose you have spent time building a memorial to their memory and there's no shame in either color scheme.
