In lighting technology, additive colour mixing refers to the mixing of coloured light by adding spectral ranges. The primary colours of additive colour mixing are the complementary colours red, green and blue. The uniform mixing of the three primary colours generates white light.
Thus, the additive colour mixing of red, green and blue results in the following secondary colours:
Good to know:
In additive colour mixing, when the three primary colours are evenly combined they produce the tertiary colour white, which appears the brightest.
Additive and subtractive colour mixing differ in that in the variant described above, colour is added or colours are combined, whereas with subtractive colour mixing they are subtracted, meaning removed and/or absorbed, e.g. with use of filters.
