At night the only color that will not damage your night vision is
red. The yellow and green cyalume lights will ruin your night vision
completely.  Red has no effect.

I've heard it said lately that the color of the light is not so
important as its intensity -- that a dim white light will not harm
night vision more than a dim red light. I have also seen references
to the military using green lighting to protect night vision.

Jack, what do you know about this?
