We've seen all kinds of ways to add color to a room - wall treatments, colorful textiles and accessories, and painted floors. We suspect the least painted surface in any room is the ceiling but don't count it out when thinking about color.
A ceiling painted a bright color might be out of the ordinary but look at the effect it has on this otherwise white room. Besides the obvious tomato red ceiling, the red paint gives off a soft pink glow to the rest of the room. Anybody want to give it a try?
