[yt-users] Can these colormaps be imported?

[Nathan Goldbaum]

It's likely possible to make it so yt automatically imports the colormaps
from these packages if they're installed. We currently do that for
colormaps from cmocean and palettable if they are installed in the same
python environment as yt. You can see how that works for cmocean right here:

https://github.com/yt-project/yt/blob/master/yt/visualization/color_maps.py#L160

I'd +1 a pull request that did something similar for the packages you
suggested.
