Paging Ed Grune, pick up the white courtesy phone.....

Ed, I have a problem researching a couple of the cruisers I want to do. How do you tell if ships painted in early 1945 in Ms 21 or 22 used the older Navy Blue system or the 1945 revised Ms 21/22 with the neutral gray colors? I am interested in the USS St Louis, CL-49, and the USS St Paul, CA-73, both repainted in early 1945 and both in Ms 21. The B&W photos are inconclusive as to the shades used. Are there any records that would help separate the two schemes? I've looked all through the S&S US Ships Camouflage site and have found nothing other than the listing of ship color schemes during the war, but that doesn't indicate whether the ships in 1945 carried the Navy Blue or Navy Gray schemes.
