Pure & vivid colours

About pure & vivid colours
Pure colours

A pure colour is a single unique spectral colour and so a fully saturated colour produced by a single wavelength of light.

  • In the context of colour, purity and saturation refer to the intensity of a hue.
  • Unsaturated colours on the other hand can appear to be:
    • Misty or milky the nearer they are to white.
    • Dull and washed out as their hue disappears, leaving achromatic grey tones.
Vivid colours

The vividness of a colour refers to its brightness.

  • When a colour is at its most vivid then it is at maximum brightness (100%).
  • As colours lose their brightness they appear progressively darker in tone until at minimum brightness they appear black (0%).
