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.
