Color is the most noticeable of the design elements and has a major influence on the appearance and feel of a room. Light colors make it appear larger. Dark colors make it appear smaller. Warm colors (reds, yellows, oranges) add excitement to a room. Cool colors (blues, greens, purples) make it restful. Neutral colors are black, white, beiges and browns. Everyone has a favorite color but should be aware of its effect.
