Perhaps because I'm prone to hibernation, I'm a big fan of dark walls. I find them embracing in the cold seasons and a refreshing break from the blinding sun in summer. Contrary to popular belief, they don't make small spaces feel smaller. In a large room, they create drama or add coziness where white walls can feel stark and unfriendly. Teal, or peacock blue, adds warmth and richness to the barest of rooms. With the addition of beautiful art and choice furniture, a teal room can feel like a walk-in jewelry box. Then again, it is a member of the family of jewel tones.
