Good question (although you have a U boat?) Blue also has night vision retention properties. I think the Americans used green interior lights for their tanks during WW2. They also use a green-white paint for some interiors because psychologically, according to studies, it is the best colour for cramped interiors.Interesting!
Brit subs always used red! I wonder what the science was behind using blue!!!
Im just speculating here, but maybe the subterranean maps used in U boats had red contour lines? Red light would render them almost invisible. As it was safer to attack at night and many U Boat attacks were carried out on the surface, night vision was still a requisite for using the deck weapons
