Dark (creepy) fog

Hey,

I know how to change the colour of fog and all, and the fog I created does have the right colour but it is too light, ie Ive got a light blue but I want a dark blue tending to black sort of fog. Does that have to do with the colour coding or with something else? Thx in advance

If it's too light a color, couldnt you lower the tinting #'s ie: if blue=100, green=100, and red=50, change to blue=50, green=50, red=25.

or something liek that.
