Hi folks,
For a long time we've used "algae," which was designed by Britton about eight years ago, as the default colormap. This has been really nice for "branding" yt -- if you see an algae plot, it's probably (not definitely) made with yt. But it's also not accessible from a colorblindness perspective. Stefan van der Walt has been giving some really great talks lately about building a better colormap for matplotlib (e.g., https://www.youtube.com/watch?v=xAoljeRJ3lU ) which culminated in viridis, which is shipping in recent versions of matplotlib and will become the default.
In support of this, he built a tool called viscm which can generate reduced versions of colormaps to show what they would be like with varying degrees of insensitivity to color. I've generated outputs from viscm of three of the custom colormaps we ship with yt:
Algae: https://images.hub.yt/u/fido/m/d275d5e1-png/ Cubehelix: https://images.hub.yt/u/fido/m/8e698928-png/ (I believe this is now also shipped with MPL) Kamae: https://images.hub.yt/u/fido/m/e0e40efa-png/
I love algae, but it's not the best from an accessibility perspective.
I'd like to propose that we use a new default colormap. If we do this, I see two options:
* Retain a "branding" by developing a new one either by using the techniques used by matplotlib (or one of the maps they opted not to use) or by modifying algae to be more accessible; looking at the response functions, I suspect it would be reasonably possible to modify it. (Modifying algae is my preference.) * Use viridis (which we may then have to ship if we have older versions of matplotlib to support)

I would also be for coming up with our own colormap. That said, I think simply modifying algae won't be enough, since it is too perceptually nonlinear.

I think there are several colourmaps that were created when Viridis was invented. I personally like Inferno.

There is a really excellent paper on designing color maps called "Color Sequences for Univariate Maps: Theory, Experiments, and Principles" that you can get here: http://ccom.unh.edu/sites/default/files/publications/Ware_1988_CGA_Color_seq...
If we design a new colormap, this would be a good reference along with those scipy resources. I personally would love to have an accessible, yt-custom colormap.

There was a fair bit of discussion about colormaps - terrible, useful, beautiful - at IEEE Vis last October. The viridis colormap was a featured one. So was the traditional rainbow, which lots of info-vis and perceptual people piled on to criticize.
Among design criteria for a continuous-valued colormap is whether it's "sequential" (like the typical yt colormap, or viridis) or "diverging". You'd want a diverging colormap to show signed deviations from a norm - where the eye should be caught by places where a value is either much less than, or much more than, something in the middle. Is it worth offering a typical divergent colormap, as well as a new typical sequential one, in yt?
Note that among the Stefan van der Walt & Nathaniel Smith writeup ( http://bids.github.io/colormap/ ) on their development of better cmaps, they use Nathan Goldbaum's galaxy evolution as a test case for six (sequential) examples! => http://vorpus.org/~njs/goldbaum-galaxies-all-colormaps.mkv
A neat web site with sample colormaps - aimed at mapping discrete values on geographic maps, so not directly applicable but cool - is this, by Cynthia Brewer and Mark Harrower at PSU: http://colorbrewer2.org/ It has a library of predesigned cmaps, and lets you sift them by being colorblind-safe, photocopy safe, etc. ________________________________ From: yt-dev [yt-dev-bounces@lists.spacepope.org] on behalf of B.W.

I am in favor of retraining a unique yt colormap but making it work better than algae for the reasons already mentioned. I'd like to point out that about a year ago I added the capacity in yt to create custom colormaps that could easily be used for this purpose.

If we design a new colormap, this would be a good reference along with those scipy resources. I personally would love to have an accessible, yt-custom colormap.

Hi folks,
For a long time we've used "algae," which was designed by Britton about eight years ago, as the default colormap. This has been really nice for "branding" yt -- if you see an algae plot, it's probably
(not
definitely) made with yt. But it's also not accessible from a colorblindness perspective. Stefan van der Walt has been giving some really great talks lately about building a better colormap for matplotlib (e.g., https://www.youtube.com/watch?v=xAoljeRJ3lU
culminated in viridis, which is shipping in recent versions of matplotlib and will become the default.
In support of this, he built a tool called viscm which can generate reduced versions of colormaps to show what they would be like with varying degrees of insensitivity to color. I've generated outputs from viscm of three of the custom colormaps we ship with yt:
Cubehelix: https://images.hub.yt/u/fido/m/8e698928-png/
this is now also shipped with MPL) Kamae: https://images.hub.yt/u/fido/m/e0e40efa-png/
I love algae, but it's not the best from an accessibility
perspective.
I'd like to propose that we use a new default colormap. If we do this, I see two options:
- Retain a "branding" by developing a new one either by using the
techniques used by matplotlib (or one of the maps they opted not to use) or by modifying algae to be more accessible; looking at the response functions, I suspect it would be reasonably possible to modify it. (Modifying algae is my preference.)
- Use viridis (which we may then have to ship if we have older
versions of matplotlib to support)

Hi Stuart and everyone else,
This is great info. I appreciate everyone's thoughtful replies.
Having both a sequential colormap (which would replace algae) and a diverging colormap, would be awesome. The Paraview devs shipped the new matplotlib ones (like Inferno) in 5.0. I think it would be a fun experiment to see if we can come up with something sufficiently "branded" or different. And then if we can't, fall back on something like Inferno?

I've experimented a bit and come up with this:
https://images.hub.yt/u/fido/m/9bbe3cf6-png/
The script:
http://paste.yt-project.org/show/6151/
This was designed with the viscm project, which is awfully cool. What do folks think? I think Kacper and Nathan also experimented with viscm and have some ideas too, so maybe we should put it up for an eventual vote.
Also, I would campaign for calling whatever our new colormap turns out to be one of these three things, in increasing order of my preference:

Having both a sequential colormap (which would replace algae) and a diverging colormap, would be awesome. The Paraview devs shipped the new matplotlib ones (like Inferno) in 5.0. I think it would be a fun experiment to see if we can come up with something sufficiently "branded" or different. And then if we can't, fall back on something like Inferno?

Among design criteria for a continuous-valued colormap is whether it's "sequential" (like the typical yt colormap, or viridis) or "diverging". You'd want a diverging colormap to show signed deviations from a norm - where the eye should be caught by places where a value is either much

Hi Stuart and everyone else,
This is great info. I appreciate everyone's thoughtful replies.
Having both a sequential colormap (which would replace algae) and a diverging colormap, would be awesome. The Paraview devs shipped the new matplotlib ones (like Inferno) in 5.0. I think it would be a fun experiment to see if we can come up with something sufficiently "branded" or different. And then if we can't, fall back on something like Inferno?

Hi Mike,
Ah, awesome. I will watch that. I do know that Ralf Kaehler designed one for the AMNH's show that was inverted from what we usually think. Sam might have reverse engineered it at some point... it'd be pretty cool to explore that type of thing as well!

Sounds good, but before we do that, I think we should have a suitable waiting period for others to propose them. I'll send an email out to yt-users asking for ideas on it.

This was designed with the viscm project, which is awfully cool. What do folks think? I think Kacper and Nathan also experimented with viscm and have some ideas too, so maybe we should put it up for an eventual vote.

Also, I would campaign for calling whatever our new colormap turns out to be one of these three things, in increasing order of my preference:

Hi Stuart and everyone else,
This is great info. I appreciate everyone's thoughtful replies.
Having both a sequential colormap (which would replace algae) and a diverging colormap, would be awesome. The Paraview devs shipped the new matplotlib ones (like Inferno) in 5.0. I think it would be a fun experiment to see if we can come up with something sufficiently "branded" or different. And then if we can't, fall back on something like Inferno?

I like middle. (and this is not based on who's it is -- but you shouldn't have told us the names)
Btw, this reminds me that I saw a very nice talk at the AAPT meeting by a UCSC graduate (Zoe ... last name escapes me). She did studies on using movies in teaching (and used a lot of Joel Primack's stuff), and worked with a range of students, and one of the conclusions is that students understood simulations of dark matter a lot better when the dark matter was colored dark instead of in bright colors. Seems obvious, in hindsight, but most of the movies you see online use bright colors / whites for high dark matter density. Her talk was very interesting, and it is nice to see someone thinking about how the color choices we make in movies affects how people learn from them.

Hi folks,

Honestly I think all could go in, but we should pick a default -- whether it's one of these or a different one. Anyone have a strong opinion?

Hi Stuart and everyone else,
This is great info. I appreciate everyone's thoughtful replies.
Having both a sequential colormap (which would replace algae) and a diverging colormap, would be awesome. The Paraview devs shipped the new matplotlib ones (like Inferno) in 5.0. I think it would be a fun experiment to see if we can come up with something sufficiently "branded" or different. And then if we can't, fall back on something like Inferno?

Among design criteria for a continuous-valued colormap is whether
it's
"sequential" (like the typical yt colormap, or viridis) or
"diverging".
You'd want a diverging colormap to show signed deviations from a
norm -
where the eye should be caught by places where a value is either
much less

offering a
typical divergent colormap, as well as a new typical sequential one,
in yt?

There is a really excellent paper on designing color maps called
"Color
Sequences for Univariate Maps: Theory, Experiments, and Principles"
that you
can get here:
http://ccom.unh.edu/sites/default/files/publications/Ware_1988_CGA_Color_seq...
If we design a new colormap, this would be a good reference along
with those
scipy resources. I personally would love to have an accessible,
yt-custom
colormap.

I think colormaps for general audience should be different by default, e.g those silly astronomers tend to use blue for hot and red for cold, even though every bathroom faucet proves them wrong...
