Colour balancing refers to the process of removing an overall colour bias from an image. It’s very important in the frame through film. Complementary colour refers to the chromatography between one of the three primary colours and its corresponding form a mutually complementary relationship.

There are three primary colours: red, yellow, blue. The three primary colours of each two groups of colours called three matching, such as red and yellow makes orange, yellow and blue makes green, blue and red makes purple, orange, green, and purple called secondary colour. Red and green, orange and blue, yellow and purple is mutually complementary relationship.

Because of the complementary colour has strong separability in colour painting's performance, in the proper position properly using the complementary colour, not only can strengthen the colour contrast, pull out the distance, but also can show the special visual contrast and effect balance.
