We recently bought a house, and the extra bedroom above the garage is marked for the Badmovies.org office. Get this: the room was painted red, with black curtains, and red carpet (and I mean the reds were "bloody murder red"). I threatened my wife with sitting in that room in the middle of the night, chanting, "Red room! Red room!" for hours, but the walls and ceiling have been repainted a calmer cream color that at least works with the red carpet.
Once we get moved in, I will take a picture or two. It will be a few years before I worry about changing the carpet, and the walls. I would like to do wood paneling in there.
If this room is going to be a Badmovies.org office, I would advise a sort of green color for the walls and floor. Should go well with the black curtains.
