The colored turret tops feature wasn't generally known until December of 2006. It's one of those facts that faded into obscurity until re-discovered by researchers.
Some clarifications to things that have been said earlier in this thread that I see need updating.
December 30th, 1940 (essentially taking affect at the beginning of 1941) the Navy ordered all shipboard aircraft to be painted in non-specular (non reflective) colors; this is when the transition from silver covered aircraft started. Arizona's aircraft would have been painted in non-specular light gray after receipt of this order, issue of paint, etc., whatever impediments a bureaucracy adds to the adoption of orders.
The October 13 order mentioned above added the blue to the mix and as we can see in the photos Arizona's Kingfishers were two-tone, but there are photos of Kingfishers on Ford Island on December 8th that are still all-over non-specular light gray.
In regards to 5-D, there is now some confusion as to its proper appearance. While looking through records of Mare Island Naval Shipyard, I found "the" formula for 5-D, which appears to be completely neutral (I.E. no blue pigment present). Mare Island was the Navy Yard responsible for paint manufacturing on the west coast (including Hawaii). Later documents reference this formula shortly before it's production was ordered stopped, yet near the bottom of this page (look for "MUNSELL DATA ON MORE PAINTS") the National Bureau of Standards reported 5-D had a Munsell value (1929 book, not today's values) of 5PB, placing it in the purple-blue range.
The more we learn, the less we know
