Out of curiosity, what are the advantages of the HCL colormap over YlGnBu for continuous values? I’m biased towards YlGnBu because green is my favorite color and want to know what makes HCL objectively better for perceiving values.
I added YlGnBu_r versions of those plots just below yours: http://nbviewer.ipython.org/gist/olgabot/6a619ef21c178801ff77
It seems it’s a little more “extreme” than HCL, as in it lights are lighter and its darks are darker. From the color research, is this less desirable?

Nathaniel’s January 9 message in that thread (can’t figure out how to
link to it in the archives) had a suggestion that I thought was very
promising, to do something similar to Parula but rotate around the hue
circle the other direction so that the hues would go blue - purple - red
- yellow. I don’t think we’ve seen an example of exactly what it would
look like, but I reckon it would be similar to the middle colormap here
(from the elegant figures block series linked above), which I’ve always
found quite attractive.

Certainly it can be considered–but we have to have a real implementation.
