colour.models.sUCS_chroma

colour.models.sUCS_chroma(Iab: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 100]) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 100]

Compute the chroma component from the sUCS colourspace.

Parameters:

Iab (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 100]) – sUCS \(Iab\) colourspace array.

Returns:

Chroma component.

Return type:

numpy.ndarray

Notes

Domain	Scale - Reference	Scale - 1
