Try this: Apply a blue tint (under video: image control) to the scene. I mapped the white rather than the black. I just sampled the blue from the default Win XP menu bar & adjusted the amount to about 90%. Then I added a brightness & contrast adjustment (video: adjust). Brightness I set to about -9 and contrast I set to about 39. Play with the settings to get just the right effect. See if that gives you the effect you want.
