Plot the *Planckian Locus* and given illuminants in
*CIE 1976 UCS Chromaticity Diagram*.
Parameters
----------
illuminants
Illuminants to plot. ``illuminants`` elements can be of any
type or form supported by the
:func:`colour.plotting.common.filter_passthrough` definition.
chromaticity_diagram_callable_CIE1976UCS
Callable responsible for drawing the
*CIE 1976 UCS Chromaticity Diagram*.
annotate_kwargs
Keyword arguments for the :func:`matplotlib.pyplot.annotate`
definition, used to annotate the resulting chromaticity coordinates
with their respective spectral distribution names. ``annotate_kwargs``
can be either a single dictionary applied to all the arrows with same
settings or a sequence of dictionaries with different settings for each
spectral distribution. The following special keyword arguments can also
be used:
- ``annotate`` : Whether to annotate the spectral distributions.
plot_kwargs
Keyword arguments for the :func:`matplotlib.pyplot.plot` definition,
used to control the style of the plotted illuminants. ``plot_kwargs``
can be either a single dictionary applied to all the plotted
illuminants with the same settings or a sequence of dictionaries with
different settings for eachplotted illuminant.
Other Parameters
