[chimerax-users] surface colouring by selected residues

[Tristan Croll]

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.
