colour.quality.ColourRendering_Specification_CIE2017

class colour.quality.ColourRendering_Specification_CIE2017(name, sd_reference, R_f, R_s, CCT, D_uv, colorimetry_data, delta_E_s)[source]

Defines the CIE 2017 Colour Fidelity Index (CFI) colour quality specification.

Parameters
  • name (unicode) – Name of the test spectral distribution.

  • sd_reference (SpectralDistribution) – Spectral distribution of the reference illuminant.

  • R_f (numeric) – CIE 2017 Colour Fidelity Index (CFI) \(R_f\).

  • R_s (array_like) – Individual colour fidelity indexes data for each sample.

  • CCT (numeric) – Correlated colour temperature \(T_{cp}\).

  • D_uv (numeric) – Distance from the Planckian locus \(\Delta_{uv}\).

  • colorimetry_data (tuple) – Colorimetry data for the test and reference computations.

  • delta_E_s (ndarray, (16,)) – Colour shifts of samples.
