class colour.quality.ColourRendering_Specification_CIE2017(name: str, sd_reference: SpectralDistribution, R_f: float, R_s: NDArrayFloat, CCT: float, D_uv: float, colorimetry_data: Tuple[DataColorimetry_TCS_CIE2017, DataColorimetry_TCS_CIE2017], delta_E_s: NDArrayFloat)[source]#

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

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

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

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

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

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

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

  • colorimetry_data (Tuple[colour.quality.cfi2017.DataColorimetry_TCS_CIE2017, colour.quality.cfi2017.DataColorimetry_TCS_CIE2017]) – Colorimetry data for the test and reference computations.

  • delta_E_s (NDArrayFloat) – Colour shifts of samples.
