The primary additive colours of light are red, green and blue, and the subtractive colours are cyan, magenta and yellow.
The resultant colours after the break down of white light into the three basic zones of the visible spectrum. The primary colours are red, green and blue. These additive primaries when combined in different amounts, will create all the colours of the visible spectrum. This principle is applied in projection television. For printing inks, the subtractive primaries of process yellow, magenta and cyan are used in combination, as percentage screens, to recreate all other colours. White is a combination of all colours, while black is the absence of all colour.
