And now, about the colored weapon lights, you are right that is already saturating,but then maybe instead of a simpler saturate model, you could use a multiplication light model like the Dodge of some paint programs and many games out there. Here i have screenshots that shows the colored light problem, even with mixed ambient light:
Image 1 (The original room, 75% white lighted entirely):

Image 2 (The same room, shooting a pure blue laser that darkens the red colors, and a light should not dark a room, since is \"light\"

I think a nicer light model should like something like this:

I hope it's not too difficult to achieve something like that, but many simple 3D Games uses some kind of multiplication light model that looks more like real light, and it really lights in all situations.
