I have a couple of his books and find them invaluable in helping me with model building techniques.
Attempting to interpret colors from black & white photos is a fool's errand, at best.
Doing so and then stating at the end that the Arizona and all the other battleships "WERE painted a dark blue color" is not offering an opinion. It's extrapolating fact from an extremely flawed experiment.
If Mike wants to post a video and say "This is why I think it's blue", I think (most) people would be far less likely to make fun of it.
And there will be a dispute over the color of the Italian fleet at Taranto when someone builds a model of the Conte di Cavour for the Regia Marina museum at La Spezia and paints it blue....
