I think what you want is the “color zone” command: 

color zone #10 near sel distance 3

... will cause each triangle on the surface to be coloured according to the colour of the nearest atom in the selection within a 3Å cutoff distance.

Dear ChimeraX community, 

I need to colour the surface by selected side chains to highlight an intermolecular contact.

The command sequence:

#select atoms on the buried surface. The selection works correctly: 

measure buriedarea #10/C:449-end withAtoms2 #9/A:449-end select true

#make a surface. A new surface #10.1 is generated:

surface #10/C resolution 7 

#color surface yellow at selected residues.

color #10 & sel yellow target s

The last command does not result in surface colouring although reports "colored 1 surfaces" upon its execution. 

Where is a mistake in the colouring approach?

I run chimeraX version 1.0 (2020-06-04) on Ubuntu 18.04.

Thank you and best regards. 

Oleksiy
