colour.temperature.CCT_to_uv_Planck1900#

colour.temperature.CCT_to_uv_Planck1900(CCT: ArrayLike, cmfs: colour.colorimetry.spectrum.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 (colour.colorimetry.spectrum.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

numpy.ndarray
