just brainstorming!;
i think that the red light is only eye-candy and it doesn't influence the NPC crewmembers but only the player(unless he sits behind his computer in a bright room).therefore would it not be possible to create a mod that creates an overlay that can be used while the normal shiplighting(white) is in on?
it schould need some extra commands to be added(red lights on/of and blue lights on/of)that overrides the ingame red lights on/of.
the idea is simple;create a full screen overlay in red and blue that are placed when the commands are used.
when leaving the interior this would give a problem but maybe by fading out on the moment you go trough the hatch(and fading in when entering the interior) this could be solved.outside the sub the red-blue schould also be inpossible to use,of course.
below i tried to give an impression how an overlay would look inside the diverse compartments.
