colour.CorrespondingColourDataset¶

class colour.CorrespondingColourDataset[source]¶

Defines a corresponding colour dataset.

Parameters

name (unicode) – Corresponding colour dataset name.
XYZ_r (array_like) – CIE XYZ tristimulus values of the reference illuminant.
XYZ_t (array_like) – CIE XYZ tristimulus values of the test illuminant.
XYZ_cr (array_like) – Corresponding CIE XYZ tristimulus values under the reference illuminant.
XYZ_ct (array_like) – Corresponding CIE XYZ tristimulus values under the test illuminant.
Y_r (numeric) – Reference white luminance \(Y_r\) in \(cd/m^2\).
Y_t (numeric) – Test white luminance \(Y_t\) in \(cd/m^2\).
B_r (numeric) – Luminance factor \(B_r\) of reference achromatic background as percentage.
B_t (numeric) – Luminance factor \(B_t\) of test achromatic background as percentage.
metadata (dict) – Dataset metadata.

Notes

This class is compatible with Luo and Rhodes (1999) Corresponding-Colour Datasets datasets.
