Combining blue and green results in cyan.
Cyan is one of the three primary colours included in the subtractive CMYK colour model. The subtractive CMYK colour model is widely used with colour printers and in colour printing in general.
On the colour wheel, cyan is located halfway between blue and green. Due to its position on the colour wheel, cyan’s complementary colour is red. Mixing cyan and red of equal intensity on a white background produces white. Similarly, red is removed from white light to produce cyan. The wavelength of cyan ranges between 490 and 520 nanometers.
