One of the often neglected but very important spaces is the ceiling. Ceilings are visually commanding, they are vast areas that get over-looked.
Now granted the photos I'm showing are over the top but you get the idea! I have used high gloss paint on low ceilings with magical results! If you don't want to use high gloss paint think a bout a subtle color. Just another design element that can make your rooms exciting!
