The Color Compass has a cool side and a warm side. Colors opposite one another on the compass are complementary. When two complementary colors are mixed they neutralize one another. This is the single most important factor of the color compass. Look at your Color Compass. You see red neutralizes green, so to get of unwanted green tones you need to add red to your formula. Understanding the Color Compass is the key to successful hair color.
