Hi Bill,
You need to get a newer version of ChimeraX (1.2 daily build).

Version 1.1 (and 1.1.1) are from August 2020, but the  "Surface Color" tool was added in March 2021, according to the change log:

<https://www.rbvi.ucsf.edu/trac/ChimeraX/wiki/ChangeLog>

This change log is a link near the top of the download page.  Also in that page, go to the daily builds section to get the current daily build.
<https://www.rbvi.ucsf.edu/chimerax/download.html>
<https://www.rbvi.ucsf.edu/chimerax/download.html#daily>

I hope this helps,
Elaine

Here is a screenshot of what I see when I look for it with both .mrc files loaded. From the hyperlink that you provided (https://rbvi.ucsf.edu/chimerax/docs/user/tools/surfacecolor.html), it appears that I could also access "Surface Color" from "Depiction" within tools, but I also cannot find "Depiction" as an option. Is there somewhere else that I should be looking for the "Surface Color" tool? Thanks ahead of time for the help.

Then in Volume Viewer, you can adjust the isosurface level of map #1 and hide the isosurface of map #2 (or you can hide it using Model Panel, same thing).   In Surface Color you would choose the (already open) models: the surface to color is model #1, you want to color it by "volume data value," and the map with values to use for coloring is #2.
