Pure colour

A pure colour is a monochromatic colour produced by a single wavelength of light.

  • Each wavelength of light at full saturation and brightness is perceived as pure colour.
  • A monochromatic colour is a colour produced by a single wavelength of light.
  • Colours produced by a narrow band of adjacent wavelengths often appear to be pure colours.
  • Spectral colours are the pure colours associated with an atmospheric rainbow.
  • Rainbow colours include red, orange, yellow, green, blue and violet but the human eye can distinguish other pure colours between each one.
  • In a continuous spectrum of sufficiently close wavelengths, separate colours are indistinguishable.
