class colour_visuals.VisualRGBColourspace2D(colourspace: RGB_Colourspace | str | Sequence[RGB_Colourspace | LiteralRGBColourspace | str] = 'sRGB', method: Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'] | str = 'CIE 1931', colour: ArrayLike | None = None, opacity: float = 1, thickness: float = 1)[source]#

Bases: MixinPropertyColourspace, MixinPropertyMethod, MixinPropertyColour, MixinPropertyOpacity, MixinPropertyThickness, Visual

Create a 2D RGB colourspace gamut visual.

Parameters:

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

  • method (Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'] | str) – Chromaticity Diagram method.

  • colour (ArrayLike | None) – Colour of the visual, if None, the colour is computed from the visual geometry.

  • opacity (float) – Opacity of the visual.

  • thickness (float) – Thickness of the visual lines.
