A uniform coloring for the walls of a series of connecting rooms contributes to unity of effect. A sufficient variety in effect may be secured by varying the color or pattern of draperies and other furnishings in the different rooms.

It seldom happens that all the rooms on a floor have the same exposure, or the same amount of light or the same use. Every need may be considered and yet a friendly harmony obtained by the use of closely related colors that may range from light to dark in value and through a series of related hues.
