Re: [Chimera-users] [chimerax-users] Color palettes - ColorBrewer support?
HI Oli, Thanks for the suggestion. I agree these would be great to have in ChimeraX, and we certainly haven’t ruled it out… but (as you know) many things are vying for developer time. I would certainly use those palettes if they were available. We’re aware of Colorbrewer and actually its palettes have been in Chimera’s Palette Editor for quite a while: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/palette.html> However, they never got interfaced with coloring by value and the only direct use was for gradient-coloring the background… admittedly not the best use of most multicolor schemes.

Hi,
I see in the help for the “rainbow” command that there is an option for web-fetched palettes – any chance for integrating support for ColorBrewer ( http://colorbrewer2.org/#)?
It has different very well-designed palettes for sequential (e.g. color by residue) divergent (e.g. color by charge or hydrophobicity) and qualitative (e.g. color by chain) data, and they are designed to be colorblind-safe etc.
It’s intended for cartography, but I have manually used their palettes for structural biology with pleasing results – the full set of palettes can be downloaded as JSON or in an excel spreadsheet.
Cheers Oli

I wrote some code to add colorbrewer schemes as colormap (palette) names, so they should be available with the "color" and "rainbow" commands (in tomorrow's daily build). Those were the most obvious uses. What are others? If they are easy, we can drop them in. Conrad On 9/8/2017 1:20 PM, Elaine Meng wrote:

Hi Conrad that’s fantastic, thanks! The only other case I can think of off hand would be scolor for coloring maps e.g. by local resolution.

Hi Oli and everybody else, In the ChimeraX daily build, the ColorBrewer palettes are available with “rainbow” (aka “color sequential”) and with the “color” command “map” option. The latter is the functional equivalent of Chimera’s “scolor” command, coloring by map value. I realize documentation is needed since the ColorBrewer website doesn’t show the names of the palettes. I plan to have this done today, to be available tomorrow on the website and in the daily build. For now, 3 important notes: (1) anybody eager to try today can use Chimera to discover the names that could be used in the ChimeraX command line (start Chimera, enter command “start Palette Editor”, choose any relevant options and click the palette of interest) (2) users should cite: www.ColorBrewer.org, color specifications and designs by Cynthia A. Brewer, Pennsylvania State University. (3) currently if coloring by map value, you cannot control the exact value-color mapping with palettes from colorbrewer or colourlovers; the colors in the palette are spaced equally along the range of values. They are quite fun to play with, as I’ve been doing today. Elaine ---------- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco
