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.
