The back panels of a bookcase or shelving unit are excellent candidates for a color accent. Tie the color into a textile or object, or choose a hue that simply makes you happy.

Accenting a white staircase with a dark paint color is as decorative as it is functional, because a dark color tends to mask scuff marks.
