colour_visuals.VisualChromaticityDiagramCIE1960UCS

class colour_visuals.VisualChromaticityDiagramCIE1960UCS(kwargs_visual_spectral_locus: dict | None = None, kwargs_visual_chromaticity_diagram: dict | None = None)

Bases: Group

Create the CIE 1960 UCS Chromaticity Diagram visual.

Parameters:

• kwargs_visual_spectral_locus (dict | None) – Keyword arguments for the underlying colour_visuals.VisualSpectralLocus2D class.

• kwargs_visual_chromaticity_diagram (dict | None) – Keyword arguments for the underlying colour_visuals.VisualChromaticityDiagram class.

Examples

>>> import os
>>> from colour.utilities import suppress_stdout
>>> from wgpu.gui.auto import WgpuCanvas
>>> with suppress_stdout():
