colour.is_within_macadam_limits

colour.is_within_macadam_limits(xyY: ArrayLike, illuminant: Literal['A', 'C', 'D65'] | str = 'D65', tolerance: float = 100 * EPSILON) → NDArrayFloat

Determine whether the specified CIE xyY colourspace array are within the MacAdam limits of the specified illuminant.

Parameters:

• xyY (ArrayLike) – CIE xyY colourspace array.

• illuminant (Literal['A', 'C', 'D65'] | str) – Illuminant name.

• tolerance (float) – Tolerance allowed in the inside-triangle check.

Returns:

Boolean array indicating whether the specified CIE xyY colourspace array is within MacAdam limits.

Return type:

numpy.ndarray
