Colour models and colour wheels

About colour models and colour wheels

• Colour wheels are used to represent colour models that can generate a complete range (gamut) of colours using three primary colours. These models include:
  • The RGB colour wheel
  • The RYB colour wheel
  • The CMY colour wheel
• The spectral colour model, which represents individual wavelengths of light in the visible spectrum, is not typically explored using colour wheels.
  • A diagram of the spectral colour model typically depicts its constituent colours in the form of a strip with red at one end and violet at the other.
