colour.plotting.RGB_scatter_plot

colour.plotting.RGB_scatter_plot(RGB, colourspace, reference_colourspace='CIE xyY', colourspaces=None, segments=8, display_grid=True, grid_segments=10, spectral_locus=False, spectral_locus_colour=None, points_size=12, cmfs='CIE 1931 2 Degree Standard Observer', **kwargs)[source]

Plots given RGB colourspace array in a scatter plot.

Parameters:
  • RGB (array_like) – RGB colourspace array.
  • colourspace (RGB_Colourspace) – RGB colourspace of the RGB array.
  • reference_colourspace (unicode, optional) – {‘CIE XYZ’, ‘CIE xyY’, ‘CIE Lab’, ‘CIE Luv’, ‘CIE UCS’, ‘CIE UVW’, ‘IPT’, ‘Hunter Lab’, ‘Hunter Rdab’}, Reference colourspace for colour conversion.
  • colourspaces (array_like, optional) – RGB colourspaces to plot the gamuts.
  • segments (int, optional) – Edge segments count for each RGB colourspace cubes.
  • display_grid (bool, optional) – Display a grid at the bottom of the RGB colourspace cubes.
  • grid_segments (bool, optional) – Edge segments count for the grid.
  • spectral_locus (bool, optional) – Is spectral locus line plotted.
  • spectral_locus_colour (array_like, optional) – Spectral locus line colour.
  • points_size (numeric, optional) – Scatter points size.
  • cmfs (unicode, optional) – Standard observer colour matching functions used for spectral locus.
Other Parameters:
