Magenta Ain't A Colour. A beam of white light is made up of all the colours in the spectrum. The range extends from red through to violet, with orange, yellow, green and blue in between. But there is one colour that is notable by its absence. You should have seen a green afterimage, but why is this significant? The afterimage always shows the colour that is complementary to the colour of the image. It is a common misconception that red is complementary to green. All the colours in the light spectrum have complements that exist within the spectrum – except green. The light spectrum consists of a range of wavelengths of electromagnetic radiation. When our eyes see colours, they are actually detecting the different wavelengths of the light hitting the retina. If the eye receives light of more than one wavelength, the colour generated in the brain is formed from the sum of the input responses on the retina.
