Eelbrain Colormaps
==================

Eelbrain adds some colormaps to `matplotlib's standard colormaps
<https://matplotlib.org/gallery/color/colormap_reference.html>`_.
In general, the colormaps come with an ``*-a`` ("alpha") version which uses
transparency for low values instead of a solid color. For example, to use the
``polar`` map with transparency, use ``polar-a``.
