That is nice! For those following along at home, here's what Eric's colormap looks like: https://bids.github.io/colormap/images/screenshots/erics_PuBuGnYl_r.png We also tried tweaking it a bit to end on a more saturated yellow, which I think helps increase contrast in the deuteranomalous version in particular, and put this on the website as an "option D": https://bids.github.io/colormap/images/screenshots/option_d.png We also previously designed a colormap that follows parula's ideas pretty closely, in terms of starting/ending points, overall brightness, and the trick of kinking over through orange at the top end. It ends up being much much more green than parula though: https://bids.github.io/colormap/images/screenshots/fake_parula.png > It seems that the fundamental constraints in this map generator tend to > yield a somewhat muddy dark end and a muted middle.

You can somewhat avoid the muddy end by bumping up the minimum brightness (option C does this to some extent), but of course that has other trade-offs. -n -- Nathaniel J.
