colour.temperature.uv_to_CCT_Planck1900#
- colour.temperature.uv_to_CCT_Planck1900(uv: ArrayLike, cmfs: MultiSpectralDistributions | None = None, optimisation_kwargs: dict | None = None) NDArrayFloat[source]#
Compute the correlated colour temperature \(T_{cp}\) of a blackbody from specified CIE UCS colourspace uv chromaticity coordinates using colour matching functions.
- Parameters:
uv (ArrayLike) – CIE UCS colourspace uv chromaticity coordinates.
cmfs (MultiSpectralDistributions | None) – Standard observer colour matching functions, default to the CIE 1931 2 Degree Standard Observer.
optimisation_kwargs (dict | None) – Parameters for
scipy.optimize.minimize()definition.
- Returns:
Correlated colour temperature \(T_{cp}\).
- Return type:
Warning
The current implementation relies on optimisation using
scipy.optimize.minimize()definition and thus has reduced precision and poor performance.References
