Please note a correction to the information supplied in the book:
For light, the primary colours are red, green and blue, from which secondary colours can be obtained, either by mixing together lights of different colours or mixing light reflected from surfaces coloured by the primary colours. The secondary colours are cyan (blue and green), magenta (red and blue) and yellow (red and green). With one of these three sets of colour, all other colour can be produced. As this experiment is about how reflected light is combined by the eye, these are the primary and secondary colours that should be used.
