colour.plotting.plot_visible_spectrum(cmfs='CIE 1931 2 Degree Standard Observer', out_of_gamut_clipping=True, **kwargs)

Plots the visible colours spectrum using given standard observer CIE XYZ colour matching functions.

Parameters

• cmfs (unicode or LMS_ConeFundamentals or RGB_ColourMatchingFunctions or XYZ_ColourMatchingFunctions, optional) – Standard observer colour matching functions used for computing the spectrum domain and colours. cmfs can be of any type or form supported by the colour.plotting.filter_cmfs() definition.

• out_of_gamut_clipping (bool, optional) – Whether to clip out of gamut colours otherwise, the colours will be offset by the absolute minimal colour leading to a rendering on gray background, less saturated and smoother.

• **kwargs (dict, optional) – {colour.plotting.artist(), colour.plotting.plot_single_sd(), colour.plotting.render()}, Please refer to the documentation of the previously listed definitions.
