I know this will probably be an Arizona color type question. Did Bismarck have red turrets during her time in the Baltic Sea in May 1941? I've seen conflicting opinions. It's either dark grey or red. I have Battleship Bismarck: A Design and Operational History that says red. I have others I have say dark grey. Various Bismarck websites seem to say dark grey. It's all very confusing.

Thanks!
