colour.colorimetry.luminance_Newhall1943(V: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 10]) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 100]

Compute the luminance \(R_Y\) from the specified Munsell value \(V\) using Newhall et al. (1943) method.

Parameters:

V (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 10]) – Munsell value \(V\).

Returns:

Luminance \(R_Y\).

Return type:

numpy.ndarray
