colour.Oklab_to_XYZ

colour.Oklab_to_XYZ(Lab: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 1]

Returns:

CIE XYZ tristimulus values.

Return type:

numpy.ndarray
