Plot given RGB colourspaces in the CIE 1931 Chromaticity Diagram.

Parameters:

colourspaces (RGB_Colourspace | str | Sequence[RGB_Colourspace | str]) – RGB colourspaces to plot. colourspaces elements can be of any type or form supported by the colour.plotting.common.filter_RGB_colourspaces() definition.
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.
chromaticity_diagram_callable_CIE1931 (Callable) – Callable responsible for drawing the CIE 1931 Chromaticity Diagram.
show_whitepoints (bool) – Whether to display the RGB colourspaces whitepoints.
show_pointer_gamut (bool) – Whether to display the Pointer’s Gamut.
chromatically_adapt (bool) – Whether to chromatically adapt the RGB colourspaces given in colourspaces to the whitepoint of the default plotting colourspace.
plot_kwargs (Dict | List[Dict] | None) – Keyword arguments for the matplotlib.pyplot.plot() definition, used to control the style of the plotted RGB colourspaces. plot_kwargs can be either a single dictionary applied to all the plotted RGB colourspaces with the same settings or a sequence of dictionaries with different settings for each plotted RGB colourspace.
kwargs (Any) – {colour.plotting.artist(), colour.plotting.diagrams.plot_chromaticity_diagram(), colour.plotting.models.plot_pointer_gamut(), colour.plotting.models.plot_RGB_colourspaces_in_chromaticity_diagram(), colour.plotting.render()}, See the documentation of the previously listed definitions.

Returns:

Current figure and axes.

Return type:

tuple
