[yt-users] Colormaps

[Cameron Hummels]

Elizabeth et al.,

Kacper, Nathan, and I have updated the docs to fix some of the issues
earlier today.  It now shows all of the colormaps applied to an individual
projection.  I also added a section to the docs on how to apply a colormap.
 For the full developer version (including the source API docs), see this
link:
