colour.plotting.plot_chromaticity_diagram_CIE1931(cmfs: MultiSpectralDistributions | str | Sequence[MultiSpectralDistributions | str] = 'CIE 1931 2 Degree Standard Observer', show_diagram_colours: bool = True, show_spectral_locus: bool = True, **kwargs: Any) → Tuple[Figure, Axes][source]#

Plot the CIE 1931 Chromaticity Diagram.

Parameters:

cmfs (MultiSpectralDistributions | str | Sequence[MultiSpectralDistributions | str]) – Standard observer colour matching functions used for computing the spectral locus boundaries. cmfs can be of any type or form supported by the colour.plotting.common.filter_cmfs() definition.
show_diagram_colours (bool) – Whether to display the Chromaticity Diagram background colours.
show_spectral_locus (bool) – Whether to display the Spectral Locus.
kwargs (Any) – {colour.plotting.artist(), colour.plotting.diagrams.plot_chromaticity_diagram(), colour.plotting.render()}, See the documentation of the previously listed definitions.

Returns:

Current figure and axes.

Return type:

tuple
