Hi folks, The current default colormap that yt uses is called "Algae," and it's been with us for a while. Recently some of us on the yt-dev mailing list (which is open to join!) have begun to look at alternate colormaps that have better characteristics, particularly from an accessibility perspective. If you have the time, it would be really, *really* helpful if you could take this anonymous, two question (only one of which is mandatory!) poll about which of the four candidates we've come up with you like the best. http://goo.gl/forms/D4qQqkPIMq Thanks very much! The poll will be open at least a week, and I'll report back the results here sometime after that. -Matt

Also if you really like one of these but we don't end up choosing it as a default, I believe we're planning on giving them all clever names and including them in yt 3.3. On Fri, Jan 29, 2016 at 11:13 AM, Matthew Turk <matthewturk@gmail.com> wrote:

can one of the alt colormaps be named hypnotoad? On Fri, Jan 29, 2016 at 12:15 PM, Nathan Goldbaum <nathan12343@gmail.com> wrote:

Hi all, The results are in! We had 54 responses. First choice: CMAP1: 5 (9.3%) CMAP2: 29 (53.7%) CMAP3: 5 (9.3%) CMAP4: 15 (27.8%) Second choice: CMAP1: 11 (20.8%) CMAP2: 6 (11.3%) CMAP3: 9 (17%) CMAP4: 27 (50.9%) Since CMAP1 got a majority, we don't need to go to instant runoff, but it looks like CMAP4 is the second choice. There were a number of comments left with the survey, available here: http://paste.yt-project.org/show/L28LFgbcV8F1SNlyZxwi/ Cameron and Nathan both asked to update their cmaps slightly to respond to comments, but I think we can include all four. Once the updated versions of CMAP2 and CMAP4 are in, I'll issue a PR that includes the following things: * The new colormaps added into our available maps * The default colormap made into a configuration variable, with its setting set to the CMAP2 name by default * Removing the matplotlib.rc() call that changes the cmap globally for all image plots * All internal-to-yt imshow and whatnot calls specifically set to using the config value for the default colormap Thanks everyone! -Matt On Fri, Jan 29, 2016 at 12:02 PM, Jill Naiman <jnaiman@gmail.com> wrote:

I've tweaked the colormap I proposed a bit so it looks less like viridis: http://imgur.com/dAFywTw Colormap script here: http://paste.yt-project.org/show/6282/ Compared to viridis and the old version, the bottom of the colormap is a bit brighter (less purple, more red), and the middle emphasizes blue colors a bit more than green colors. I like the name 'arbre' for this colormap. Does anyone hate the modifications I've made? On Wed, Feb 10, 2016 at 12:53 PM, Matthew Turk <matthewturk@gmail.com> wrote:

Hi Nathan, I like it, and I like the name even if it is a tad less pronounceable. :) If nobody objects, I'll update my colormap bookmark with this change. -Matt On Tue, Mar 1, 2016 at 3:10 PM, Nathan Goldbaum <nathan12343@gmail.com> wrote:
