Plot the visible spectrum volume, i.e. Rösch-MacAdam colour solid, section colours along given axis and origin.

Parameters:

cmfs (MultiSpectralDistributions | str | Sequence[MultiSpectralDistributions | str]) – Standard observer colour matching functions, default to the CIE 1931 2 Degree Standard Observer. cmfs can be of any type or form supported by the colour.plotting.common.filter_cmfs() definition.
illuminant (SpectralDistribution | str) – Illuminant spectral distribution, default to CIE Illuminant D65. illuminant can be of any type or form supported by the colour.plotting.common.filter_illuminants() definition.
model (Literal['CAM02LCD', 'CAM02SCD', 'CAM02UCS', 'CAM16LCD', 'CAM16SCD', 'CAM16UCS', 'CIE Lab', 'CIE Luv', 'CIE UCS', 'CIE UVW', 'CIE XYZ', 'CIE xyY', 'DIN99', 'Hunter Lab', 'Hunter Rdab', 'ICaCb', 'ICtCp', 'IPT', 'IPT Ragoo 2021', 'IgPgTg', 'Jzazbz', 'OSA UCS', 'Oklab', 'Yrg', 'hdr-CIELAB', 'hdr-IPT'] | str) – Colourspace model, see colour.COLOURSPACE_MODELS attribute for the list of supported colourspace models.
axis (Literal['+z', '+x', '+y'] | str) – Axis the hull section will be normal to.
origin (float) – Coordinate along axis at which to plot the hull section.
normalise (bool) – Whether to normalise axis to the extent of the hull along it.
show_section_colours (bool) – Whether to show the hull section colours.
show_section_contour (bool) – Whether to show the hull section contour.
kwargs (Any) – {colour.plotting.artist(), colour.plotting.render(), colour.plotting.section.plot_hull_section_colours() colour.plotting.section.plot_hull_section_contour()}, See the documentation of the previously listed definitions.

Returns:

Current figure and axes.

Return type:

tuple
