The living and dining rooms, which occupy opposite ends of one large space, provide lessons in decorating with color, reflecting the various hues of a rich sunset. The golden yellow walls are an effective backdrop for the bright red sofa, red dining room chairs, and multicolored contemporary rug. Shade panels hung on brushed-nickel curtain rods spread the sunset tones around the two rooms. SOFA AND WINDOW PANELS: Ethan Allen.
