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.

Hi folks,
I've put up a comparison image:

Left is Kacper, middle is me, right is Nathan.
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?

Wow, all of these look great. I think I like Matt's best for painting our bikeshed, but I would be happy with any of them.

Hi all,
I've experimented a bit and come up with this:

The script:

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.
This is my experiment:

Cheers, Kacper
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:
