Plot the blue sky spectral radiance distribution.

Parameters:

cmfs (MultiSpectralDistributions | str | Sequence[MultiSpectralDistributions | str]) – 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.common.filter_cmfs() definition.
kwargs (Any) – {colour.plotting.artist(), colour.plotting.plot_single_sd(), colour.plotting.plot_multi_colour_swatches(), colour.plotting.render()}, See the documentation of the previously listed definitions.
