colour.Luv_to_uv

colour.Luv_to_uv(Luv: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 100], illuminant: ArrayLike = CCS_ILLUMINANTS['CIE 1931 2 Degree Standard Observer']['D65']) → NDArrayFloat

Convert from CIE L*u*v* colourspace to \(uv^p\) chromaticity coordinates.

Parameters:

• Luv (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 100]) – CIE L*u*v* colourspace array.

• illuminant (ArrayLike) – Reference illuminant CIE xy chromaticity coordinates or CIE xyY colourspace array.

Returns:

\(uv^p\) chromaticity coordinates.

Return type:

numpy.ndarray

Notes

Domain	Scale - Reference	Scale - 1
Luv	100	1
illuminant	1	1
