colour.RGB_to_IHLS

colour.RGB_to_IHLS(RGB: 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]

Convert from RGB colourspace to IHLS (Improved HLS) colourspace.

Parameters:

RGB (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – RGB colourspace array.

Returns:

HYS colourspace array.

Return type:

numpy.ndarray
