colour.is_within_pointer_gamut#

colour.is_within_pointer_gamut(XYZ: ArrayLike, tolerance: float = 100 * EPSILON) → NDArrayFloat[source]#

Return whether given CIE XYZ tristimulus values are within Pointer’s Gamut volume.

Parameters:

XYZ (ArrayLike) – CIE XYZ tristimulus values.
tolerance (float) – Tolerance allowed in the inside-triangle check.

Returns:

Whether given CIE XYZ tristimulus values are within Pointer’s Gamut volume.

Return type:

numpy.ndarray
