colour.temperature.CCT_to_uv_Planck1900#
- colour.temperature.CCT_to_uv_Planck1900(CCT: ArrayLike, cmfs: MultiSpectralDistributions | None = None) NDArrayFloat [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 (ArrayLike) – Colour temperature \(T_{cp}\).
cmfs (MultiSpectralDistributions | None) – Standard observer colour matching functions, default to the CIE 1931 2 Degree Standard Observer.
- Returns:
CIE UCS colourspace uv chromaticity coordinates.
- Return type:
