Color is psychologically important.
It can affect not only the apparent size of a space, but the temperature and mood of a room. The use of warm or cool colors depends on personal preferences, climate and the orientation of your home. Blues and greens often are preferred in rooms having natural light and southern exposure. Warmer colors may be preferred in rooms having northern exposure and little natural light. Dark rooms might be made lighter using the pastel tones of warm or cool colors.
