colour.CorrespondingColourDataset#
- class colour.CorrespondingColourDataset(name, XYZ_r, XYZ_t, XYZ_cr, XYZ_ct, Y_r, Y_t, B_r, B_t, metadata)[source]#
Define a corresponding colour dataset.
- Parameters
name – Corresponding colour dataset name.
XYZ_r – CIE XYZ tristimulus values of the reference illuminant.
XYZ_t – CIE XYZ tristimulus values of the test illuminant.
XYZ_cr – Corresponding CIE XYZ tristimulus values under the reference illuminant.
XYZ_ct – Corresponding CIE XYZ tristimulus values under the test illuminant.
Y_r – Reference white luminance \(Y_r\) in \(cd/m^2\).
Y_t – Test white luminance \(Y_t\) in \(cd/m^2\).
B_r – Luminance factor \(B_r\) of reference achromatic background as percentage.
B_t – Luminance factor \(B_t\) of test achromatic background as percentage.
metadata – Dataset metadata.
Notes
This class is compatible with Luo and Rhodes (1999) Corresponding-Colour Datasets datasets.
