Even the 0.01% of WWII photos taken in color, the colors seen in multiple generation images can't be trusted as to true hue.
You have said before that your proof are images gleaned from the internet and other sources that you have CHERRY-PICKED and that you BELIEVE are the true colors. If I went by your method, 5-N used for most of the war for on use of models would look like various shades of Ocean Gray. We know what the various paints looked like from samples made from the original paints (I have seen some of them as sample swatches in textual records at NARA).
It is really hard for USN crews to paint their ship with a paint that didn't exist when the ship was painted. In late December 1944 and early January 1945 there likely wasn't any supply of the new paints available at HPNY to paint USS ALASKA given how long it takes to ramp up production and with INSTRUCTIONS to use up EXISTING stocks of paint first.
Believe that or not, it doesn't matter to me for your models. But, don't try to state that your beliefs are FACT.
