The colours you choose will depend on your personal tastes and preferences. Colours are intricately linked with mood, and can elevate or depress your spirits. For rooms that require rest and repose, opt for cooler colours from the blue, green and lavender families. Pastels will work very well in such spaces, while dark colours may be overwhelming and depressing. For rooms that are about energy and vitality, such as living rooms, family rooms or home offices, try warm colours from the red, orange and yellow families. Mild warm shades such as peach and lemon yellow create happy atmospheres. Of course, vibrant colours must be used carefully; try to restrict them to feature walls or décor accents such as furnishings or art. For smaller, darker spaces, use light colours to liven them up and create an illusion of space. Using neutral colours also helps you play off your prized objects.
