colour.colorimetry.dataset.cmfs Module

Colour Matching Functions Spectral Power Distributions

Defines various colour matching functions involved in spectral computations.

The colour matching functions data is in the form of a dict of colour.colorimetry.spectrum.TriSpectralPowerDistribution classes as follows:

{'name': TriSpectralPowerDistribution,
...,
'name': TriSpectralPowerDistribution}

The following colour matching functions are available:

  • Stockman & Sharpe 2 Degree Cone Fundamentals [1]
  • Stockman & Sharpe 10 Degree Cone Fundamentals [1]
  • Wright & Guild 1931 2 Degree RGB CMFs [2]
  • Stiles & Burch 1955 2 Degree RGB CMFs [3]
  • Stiles & Burch 1959 10 Degree RGB CMFs [4]
  • CIE 1931 2 Degree Standard Observer [5]
  • CIE 1964 10 Degree Standard Observer [5]
  • CIE 2012 10 Degree Standard Observer [6]
  • CIE 2012 2 Degree Standard Observer [6]
