colour.CCT_to_uv

colour.CCT_to_uv(CCT_D_uv, method='Ohno 2013', **kwargs)[source]

Returns the CIE UCS colourspace uv chromaticity coordinates from given correlated colour temperature \(T_{cp}\) using given method.

Parameters:
  • CCT_D_uv (ndarray) – Correlated colour temperature \(T_{cp}\), \(\Delta_{uv}\).
  • method (unicode, optional) – {‘Ohno 2013’, ‘Robertson 1968’, ‘Krystek 1985}, Computation method.
Other Parameters:
 

cmfs (XYZ_ColourMatchingFunctions, optional) – {colour.temperature.CCT_to_uv_Ohno2013()}, Standard observer colour matching functions.
Returns:

CIE UCS colourspace uv chromaticity coordinates.
Return type:

ndarray
