colour.quality.ColourRendering_Specification_CRI#

class colour.quality.ColourRendering_Specification_CRI(name: str, Q_a: float, Q_as: Dict[int, DataColourQualityScale_TCS], colorimetry_data: Tuple[Tuple[DataColorimetry_TCS, ...], Tuple[DataColorimetry_TCS, ...]])[source]#

Define the Colour Rendering Index (CRI) colour quality specification.

This dataclass represents the colour quality assessment results using the CRI method, which evaluates how accurately a light source renders colours compared to a reference illuminant.

Parameters:

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

  • Q_a (float) – Colour Rendering Index (CRI) \(Q_a\) general index value.

  • Q_as (Dict[int, DataColourQualityScale_TCS]) – Individual colour rendering indexes data for each test colour sample.

  • colorimetry_data (Tuple[Tuple[DataColorimetry_TCS, ...], Tuple[DataColorimetry_TCS, ...]]) – Colorimetry data for the test and reference illuminant computations.
