Flow the Color
In order to create a flow of colors from one room to another, simply choose a color you're using in one room and restate it in a different way in an adjoining space. For example, if your sofa is green, use the same green for seat fabric in the dining room.

Use the color in larger or smaller degrees as you move about the home. That same green from the living room sofa mentioned above can also translate as, say, lampshades in the family room or place mats in the kitchen.
