Thank you. The answers from Elaine Meng and Tom Goddard are definitely what I was looking for.

Hi Darrell,

You need to use the multiscale coloring command "msc". Here's an example
using Chimera commands (Favorites / Command Line):

open viperID:1p58
color blue :86.A
msc #1 :86.A 15

The first command opens a dengue virus model from the VIPERdb database.
Then I color residue 86 of chain A blue. That just colors the atoms of
the residue not the surface. Then the msc command colors the multiscale
surfaces (model identifier #1 seen in Favorites / Model Panel) making
the surface color match the blue of residue 86 within 15 Angstroms of
that residue.

After I open the model and before coloring it I can change its
resolution by pressing the Select All button at the top of the
Multiscale dialog, then change the Resolution value in the middle of
that dialog and press Resurface. A resolution value of 0 will make very
high resolution solvent excluded molecular surfaces. The lighting
effects will look better on lower resolution surfaces (e.g. 5 Angstroms).

I've attached an example image.

Tom
