Tony is right.  And the Surface Color user interface panel from Chimera has not been implemented in ChimeraX so you have to use the "color sample" command.  I may add the Surface Color user interface panel in the next week or two since I am working on adding missing volume data user interfaces in ChimeraX right now.

Colton,

I think you're looking for the sample and map keywords of the color​ command. I'm not sure if there's a tool for doing this like the Surface Color tool in Chimera. 

https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#sample

For example, I've got an electron isodensity surface in model #1 and the ESP in model #2. I can color the electron density based on the ESP with

`color sample #1 map #2 palette -0.024,red:-0.012,yellow:0,green:0.012,cyan:0.024,blue` 

This will color #1 rainbow colors based on the ESP values between -0.024 to 0.024 from #2. The custom palette specification is the thresholds levels and colors separated by commas, with each of those separated by colons.

I used color names, but there are several other ways to specify colors:

Hello,

I am just wondering if ChimeraX has added the ability to colour surfaces based on the values of a different surface? That is, input 2 cube files, then colour one cube file based on the values of the other. It is available in the other version of chimera, but the only information I could find on this was from 2018 and said it was not yet implemented in ChimeraX.

Thanks a bunch!
Colton
