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.
