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', 'HCL', 'HSL', 'HSV', 'Hunter Lab', 'Hunter Rdab', 'ICaCb', 'ICtCp', 'IHLS', 'IPT', 'IPT Ragoo 2021', 'IgPgTg', 'Jzazbz', 'OSA UCS', 'Oklab', 'RGB', 'YCbCr', 'YCoCg', '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
