White . . . minimalist, magical, or a little of both? The question remains if white qualifies as a real color or not. Some designers wouldn't think of creating a room sans pigment-laden appointments. Others use it as a foolproof mechanism for sophistication. In bedrooms, white and variations of it lead the way to a restful snooze. Dining rooms with white as their palettes sing in refinement and class. Teamed with black, and high-glass elements, the color reads glamorous and seductive. Warm white offers comfort. Feast your eyes on these colorless treats from show houses across the country.
