   Complementary Colors

   It is helpful to understand the concept of complementary colors when adjusting color balance. When two primary colors of the primary colors of light (RGB) or primary colors of pigment (CMY) are mixed, the resulting color is the complimentary color of the remaining primary color. Red and cyan, green and magenta, and blue and yellow are pairs of complementary colors.

   Hints for Adjusting Color Balance

   The following methods are available to make a specific color stronger: decreasing the color's complementary color or decreasing the other colors (that is, decreasing complementary colors relatively). A combination of both methods can be used.

   For example, to make red more vivid, make red stronger (by decreasing cyan) or decrease green and blue (making magenta and yellow stronger). The more red is used, the brighter the image looks. This is useful to adjust the color of a dark image. On the contrary, the less green and blue are used, the duller the image looks. Use this method to make a bright image dull.
