Hi Colton,
Yes, you can color a surface (including a map isosurface) by the values in any map model with the "color" command, specifically "color sample":

<https://rbvi.ucsf.edu/chimerax/docs/user/commands/color.html>
<https://rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#map>

You can access your downloaded copy of the User Guide from the ChimeraX Help menu, or see the copy on our website (e.g. the links above).

E.g. if the cube file shown as isosurface that you want to color is #1 and the other cube file with the values you want to use for coloring is #2 and the range of values you want to map to coloring is 0.1-0.5, something like:

color sample #1 map #2 palette puor range 0.1,0.5

... but see the links above for all the options, how to control which colors go with which values, etc.
I hope this helps,
Elaine

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.
