• The rule suggests that a room's color scheme should be composed of 60 percent of a dominant color, 30 percent of a secondary color and 10 percent of an accent color.
• The dominant color is the main color of the room, usually applied to walls, floors, and large furniture pieces.
• The secondary color supports the dominant color and is applied to curtains, rugs, and smaller pieces of furniture.
• The accent color is used sparingly and is applied to accessories, such as throw pillows, vases, and artwork.
