The colour created when one of the three red, green or blue primaries is taken away from white light.
Complementary colour
The hue most opposite to a given colour. The complementaries for blue, green and red are yellow, magenta and cyan respectively.
Complementary colours
1. Any two colours of light that when combined include all the wavelengths of light and thus produce white light.
2. Any two dye colours that when combined absorbs all wavelengths of light and thus produce black.
Underneath each layer are dye developing molecules in their complementary colours of yellow, magenta, and cyan. When light strikes an emulsion layer, it blocks the complementary dye below it.
Contrasting colours work well: the contrast of brilliant shades against murky ones, complementary colours such as red against green or the contrast of warm and cold colours such as red against blue.
Well, such colour filters have the effect of brightening areas in a photo of their own colour and darkening areas of their complementary colours.
