colour.XYZ_to_sRGB

colour.XYZ_to_sRGB(XYZ, illuminant=array([ 0.3127, 0.329 ]), chromatic_adaptation_transform='CAT02', apply_cctf_encoding=True, **kwargs)[source]

Converts from CIE XYZ tristimulus values to sRGB colourspace.

Parameters:
  • XYZ (array_like) – CIE XYZ tristimulus values.
  • illuminant (array_like, optional) – Source illuminant chromaticity coordinates.
  • chromatic_adaptation_transform (unicode, optional) – {‘CAT02’, ‘XYZ Scaling’, ‘Von Kries’, ‘Bradford’, ‘Sharp’, ‘Fairchild’, ‘CMCCAT97’, ‘CMCCAT2000’, ‘CAT02_BRILL_CAT’, ‘Bianco’, ‘Bianco PC’}, Chromatic adaptation transform.
  • apply_cctf_encoding (bool, optional) – Apply sRGB encoding colour component transfer function / opto-electronic transfer function.
Other Parameters:
 

**kwargs (dict, optional) – Keywords arguments for deprecation management.

Returns:

sRGB colour array.

Return type:

ndarray
