Color balance
From Wikipedia, the free encyclopedia
In graphics, image processing, and photography, color balance refers to the adjustment of the relative amounts of red, green, and blue primary colors in an image such that neutral gray is reproduced correctly. Color balance changes the overall mixture of colors in an image and is used for generalized color correction.
Balance is achieved by shifting the amounts of a color and its opposite on the color wheel. There are three pairs of opposite colors normally used: cyan and red, magenta and green, and yellow and blue. Increasing the amount of one decreases the amount of its opposite. Color balance is frequently adjustable in the camera and also in image manipulation programs, e.g. The Gimp and Photoshop.
