Red, green & blue light

About red, green & blue light
  • Because of the way the eye works, we can see all the colours of the visible spectrum by mixing red, green and blue lights at different intensities.
  • Red, green and blue are the three primary colours of the RGB colour model.
  • The RGB colour model replicates the response of light-sensitive cone cells in the retina at the back of our eyes sense colour.
  • Mixing wavelengths of light corresponding with the RGB primaries fools the eye into seeing almost any imaginable colour.
