colour.CCT_to_uv

colour.CCT_to_uv(CCT_D_uv: ArrayLike, method: Union[Literal['Krystek 1985', 'Ohno 2013', 'Robertson 1968'], str] = 'Ohno 2013', **kwargs: Any) → numpy.ndarray[source]

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

Parameters

  • cmfs – {colour.temperature.CCT_to_uv_Ohno2013()}, Standard observer colour matching functions.

  • kwargs (Any) –

Returns
