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 thecolour.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 thecolour.plotting.common.filter_illuminants()
definition.model (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) – 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.
