Yes, the same CINCAF message was also reproduced in an old issue of
Warship International many years ago, which is how I first came across it...
CA-30 had 200 workmen aboard her for much of the final month [Nov 1941] at NY Cavite doing the last-minute stuff, so it's possible she was painted at that point. But, I've never read of anybody who was there saying they remembered painting her then, or later. In view of the alterations to her at that stage, I think repainting might have been problematic, but that is just speculation. They were
definitely working w/her searchlights & the platforms for those, along with the 1.1" guns & those areas, and may have been fiddling again w/her degaussing gear.
By Dec 6, she was at Iloilo, and no one ever recalls painting her there/then.
However, I do
not claim to be authoritative on this mysterious subject, which has gone on now for decades.
One may draw one's own conclusions from the last good images of her--those taken at Darwin.

I have seen original photos of her being repainted at Cavite in the P.I. after she became flagship again, and the darker gray is quite noticeable. That it became so light by later in '41, or during the war, as shown in the few images of
Houston that survived tells us much about how lacking in durability the Cavite Blue really was.
