> I particularly like that A ends on the white end of the spectrum That's exactly why I don't like A that much. In many plots, I need a color for NaN results. This color should not fall within the normal range of the colormap. In case of B and C, it would be possible to use white as NaN color.

It's astonishing how many different opinions we have! Anyway, first of all, a big thank you to Nathaniel and Stéfan for some kick-ass work. I'm amazed at the perceptual delta results for Parula... 8-O Good to know that MPL will not make the same mistake. Second, my preferences: A > B > C. I par

1. C 2. B 3. A But I wouldn't call them aesthetic - the purple in there just looks off - I'd prefer something like hot, afmhot, or gist_heat - or variations on those. Since this thread is bound to get plenty of attention (I suggest getting feedback from -users, too), we would be remiss if we didn

Great work! Very nice post describing the methodology. I especially like the choice of images you used to expose differences between colormaps. My ranking is: 1. C 2. A 3. B To my eyes, C has the highest dynamic range (somehow the opposite of Eric!) and I like the purple/blue undertone in the dar

Sorry for send you two emails, Nathaniel. I'm going to vote for A with C as a close second. Of the three, B looks the most "bandy" to me (but not overly so). -p On Tue, Jun 2, 2015 at 6:46 PM, Nathaniel Smith wrote: > Hi all, > > As was hinted at in a previous thread, Stéfan van der Walt and I

Hi all, As was hinted at in a previous thread, Stéfan van der Walt and I have been using some Fancy Color Technology to attempt to design a new colormap intended to become matplotlib's new default. (Down with jet!) Unfortunately, while our Fancy Color Technology includes a computational model of
