2017	Reversing color palettes	olibclarke@…	Conrad Huang	"{{{
The following bug report has been submitted:
Platform:        Darwin-18.6.0-x86_64-i386-64bit
ChimeraX Version: 0.9 (2019-06-05)
Description
Minor feature request re palettes:

The Colorbrewer palettes are great, and I love that we can easily select how many colors to interpolate through by changing the name.

Would it be possible to add a similar modifier (e.g. ""R"") to the end to reverse the palette? This would be useful when using these palettes for rainbow coloring - e.g. I like the RdYlBu-5 palette for rainbow coloring protein molecules, but it is the wrong way around for the conventional N=Blue --> C=Red coloring.

(or maybe a ""reverse"" keyword for the rainbow or color sequential command would do the trick)

Cheers
Oli
