On a nuclear submarine the control room lights get turned off completely when going to periscope depth at night. Only faint lights from indicator panels illuminate the control room.

In the sonar room there is white lighting but only the blue lighting is used when sonar is manned. Reason being for this is it helps to contrast the green light being emitted from the CRT screens.

As for berthing areas those are kept dark with usually a single red light to provide enough light to see into your rackpan or locker.
