Hi Eric, The coulombic comand does not produce a map of electrostatic potential by default, so the Surface Color that colors a surface using map values will not be of use. Instead you can use the coulombic command "range" option, for example coulombic sel range -5,5 This is explained in the coulombic command documentation with an example here https://www.cgl.ucsf.edu/chimerax/docs/user/commands/coulombic.html#palette-...

I want to have less white and more color on an electrostatic potential map. I suspect this is done by reducing the range, but I can't find how to do this. I start with
open 1bl8 fromDatabase pdb format mmcif select protein coulombic sel ui tool show "Surface Color"
Then I have this dialog, where I have changed -10 ... +10 to -5 ... +5

When I click the Color button, I get "No map chosen for coloring", but the "using map" menu has no options.
???
Also I would like to re-color the surfaces for all 4 chains, not one at a time, but the "Color surface" menu seems to have 4 separate chain surfaces, but no option for all 4 at once.
I will appreciate guidance!
