Additive Colour Mixing

The mixing of coloured lights (lights containing limited ranges of wavelengths) by superimposing them to reflect off the same surface. It is additive because each light adds to global wavelengths reflected to the eye.

A coloured light is made up of a particular wavelength, by mixing coloured lights we are actually adding different wavelengths together, leading to our brains perceiving a new colour, this is known as additive colour mixing.
