colour.plotting.plot_RGB_chromaticities_in_chromaticity_diagram_CIE1931(RGB: ArrayLike, colourspace: RGB_Colourspace | str | Sequence[RGB_Colourspace | str] = 'sRGB', chromaticity_diagram_callable_CIE1931: Callable = plot_RGB_colourspaces_in_chromaticity_diagram_CIE1931, scatter_kwargs: Dict | None = None, **kwargs: Any) → Tuple[Figure, Axes][source]#

Plot given RGB colourspace array in the CIE 1931 Chromaticity Diagram.

Parameters:

RGB (ArrayLike) – RGB colourspace array.
colourspace (RGB_Colourspace | str | Sequence[RGB_Colourspace | str]) – RGB colourspace of the RGB array. colourspace can be of any type or form supported by the colour.plotting.common.filter_RGB_colourspaces() definition.
chromaticity_diagram_callable_CIE1931 (Callable) – Callable responsible for drawing the CIE 1931 Chromaticity Diagram.
scatter_kwargs (Dict | None) –
Keyword arguments for the matplotlib.pyplot.scatter() definition. The following special keyword arguments can also be used:
- c : If c is set to RGB, the scatter will use the colours as given by the RGB argument.
kwargs (Any) – {colour.plotting.artist(), colour.plotting.diagrams.plot_chromaticity_diagram(), 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
