Your ceiling design options go beyond whether to stay with a traditional flat, bright white surface or a ceiling with "popcorn" or some other texture. Your ceiling doesn't even have to be white. For a simple and inexpensive but dramatic change, consider painting your ceiling the same shade as the other walls of your room. Some design experts recommend painting your ceiling a lighter shade of the same color as your walls. Consider the colors you're using throughout the room, even in your accessories. You could also have a mural painted on the ceiling. Favorites for bedrooms include clouds, stars and other sky scenes.
