The best color to paint your office with is off-white (something that is no very stark and sterile looking!) accented with a bold color. The off-white will help bounce natural light around your workspace. The bold color will add a splash of life to your space and help boost your mood. If you want extra passion and energy, consider red as the bold color, but if you have a high-stress job or work environment, consider blues or greens for their calming effects.
