colour.volume.macadam_limits Module¶

Optimal Colour Stimuli - MacAdam Limits¶

Defines objects related to optimal colour stimuli computations.

colour.volume.macadam_limits.is_within_macadam_limits(xyY, illuminant)[source]¶

Returns if given CIE xyY colourspace matrix is within MacAdam limits of given illuminant.

Parameters:	xyY (array_like, (3,)) – CIE xyY colourspace matrix. illuminant (unicode) – Illuminant.
Returns:	Is within MacAdam limits.
Return type:	bool

Notes

• Input CIE xyY colourspace matrix is in domain [0, 1].
• This definition requires scipy to be installed.
