colour.temperature.CCT_to_uv_Planck1900#

colour.temperature.CCT_to_uv_Planck1900(CCT: FloatingOrArrayLike, cmfs: Optional[MultiSpectralDistributions] = None) ndarray[source]#

Return the CIE UCS colourspace uv chromaticity coordinates from given correlated colour temperature \(T_{cp}\) and colour matching functions using the spectral radiance of a blackbody at the given thermodynamic temperature.

Parameters:
  • CCT (FloatingOrArrayLike) – Colour temperature \(T_{cp}\).

  • cmfs (Optional[MultiSpectralDistributions]) – Standard observer colour matching functions, default to the CIE 1931 2 Degree Standard Observer.

Returns:

CIE UCS colourspace uv chromaticity coordinates.

Return type:

numpy.ndarray
