=====================


New colormap
------------
In heatmaps, a green-to-red spectrum is often used to indicate intensity of
activity, but this can be problematic for the red/green colorblind. A new,
colorblind-friendly colormap is now available at :class:`matplotlib.cm.Wistia`.
This colormap maintains the red/green symbolism while achieving deuteranopic
legibility through brightness variations. See
`here <https://github.com/wistia/heatmap-palette>`
for more information.
