colour.plotting.plot_RGB_colourspaces_gamuts(colourspaces: RGB_Colourspace | LiteralRGBColourspace | str | Sequence[RGB_Colourspace | LiteralRGBColourspace | str], model: LiteralColourspaceModel | str = 'CIE xyY', segments: int = 8, show_grid: bool = True, grid_segments: int = 10, show_spectral_locus: bool = False, spectral_locus_colour: ArrayLike | str | None = None, cmfs: MultiSpectralDistributions | str | Sequence[MultiSpectralDistributions | str] = 'CIE 1931 2 Degree Standard Observer', chromatically_adapt: bool = False, convert_kwargs: dict | None = None, **kwargs: Any) → Tuple[Figure, Axes3D]

Plot the gamuts of the specified RGB colourspaces in the specified reference colourspace.

Parameters:

• colourspaces (RGB_Colourspace | LiteralRGBColourspace | str | Sequence[RGB_Colourspace | LiteralRGBColourspace | str]) – RGB colourspaces to plot the gamuts of. colourspaces elements can be of any type or form supported by the colour.plotting.common.filter_RGB_colourspaces() definition.

• model (LiteralColourspaceModel | str) – Colourspace model, see colour.COLOURSPACE_MODELS attribute for the list of supported colourspace models.

• segments (int) – Edge segments count for each RGB colourspace cube.

• show_grid (bool) – Whether to show a grid at the bottom of the RGB colourspace cubes.

• grid_segments (int) – Edge segments count for the grid.

• show_spectral_locus (bool) – Whether to show the spectral locus.

• spectral_locus_colour (ArrayLike | str | None) – Spectral locus colour.

• 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.

• chromatically_adapt (bool) – Whether to chromatically adapt the RGB colourspaces specified in colourspaces to the whitepoint of the default plotting colourspace.

• convert_kwargs (dict | None) – Keyword arguments for the colour.convert() definition.

• edge_colours – Edge colours array such as edge_colours = (None, (0.5, 0.5, 1.0)).

• edge_alpha – Edge opacity value such as edge_alpha = (0.0, 1.0).

• face_alpha – Face opacity value such as face_alpha = (0.5, 1.0).

• face_colours – Face colours array such as face_colours = (None, (0.5, 0.5, 1.0)).

• kwargs (Any) – {colour.plotting.artist(), colour.plotting.volume.nadir_grid()}, See the documentation of the previously listed definitions.

Returns:

Current figure and axes.

Return type:

tuple
