Plot given RGB colourspaces gamuts in given reference colourspace.

Parameters

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

  • reference_colourspace (Union[Literal[('CAM02LCD', 'CAM02SCD', 'CAM02UCS', 'CAM16LCD', 'CAM16SCD', 'CAM16UCS', 'CIE XYZ', 'CIE xyY', 'CIE Lab', 'CIE Luv', 'CIE UCS', 'CIE UVW', 'DIN99', 'Hunter Lab', 'Hunter Rdab', 'ICaCb', 'ICtCp', 'IPT', 'IgPgTg', 'Jzazbz', 'OSA UCS', 'Oklab', 'hdr-CIELAB', 'hdr-IPT')], str]) – Reference colourspace model to plot the gamuts into, see colour.COLOURSPACE_MODELS attribute for the list of supported colourspace models.

  • segments (Integer) – Edge segments count for each RGB colourspace cubes.

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

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

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

  • spectral_locus_colour (Optional[Union[ArrayLike, str]]) – Spectral locus colour.

  • cmfs (Union[MultiSpectralDistributions, str, Sequence[Union[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.filter_cmfs() definition.

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

  • convert_kwargs (Optional[Dict]) – 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
