colour.optimal.dataset.optimal_colour_stimuli Module¶

Optimal Colour Stimuli¶

Defines MacAdam optimal colour stimuli for various illuminants in CIE xyY colourspace.

The optimal colour stimuli data is in the form of a dict of tuple as follows:

{'name': tuple, ..., 'name': tuple}

where each tuple contains a collection of optimal colour stimulus tuple as follows:

(('x', 'y', 'Y'), ..., ('x', 'y', 'Y'))
