colour.CorrespondingColourDataset

class colour.CorrespondingColourDataset(name, XYZ_r, XYZ_t, XYZ_cr, XYZ_ct, Y_r, Y_t, B_r, B_t, metadata)[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.
