[Chimera-users] coloring only specific atoms, or atoms but not ribbon

If you are coloring your selection with the menu, choose menu: Actions… Color… all options (it’s at the bottom of the menu). That will open a separate Color Actions dialog, in which you could set the “Color applies to” to “atoms/bonds” to color atoms/bonds only, or “ribbons” to color ribbon segment only, etc. (default is “all of the above”).
If you first display the atoms of the residue, you can Ctrl-click to select a specific atom instead of the whole residue.
If you are using the “color" command, you control which types of displays are affected by putting some text right after the color name.
color red,a sel
…. which colors atoms/bonds only, indicated by the “,a” (no space before it!!), and instead of selecting and using “sel” you can give residue and atom information directly:
color red,a :55.A at ND1
… to color atom ND1 of residue 55 in chain A, or
color hot pink,r :55.A
… to color ribbon-only (indicated by “,r”) of residue 55 in chain A
The getting-started tutorials include examples of these, but I know it can be hard to find exactly what you want.
I hope this helps,
