oh yes! thanks so much! how neat!

Hi Liz, The “at” symbol is for atom names (in both Chimera and ChimeraX), so the commands you gave would work only to color the atoms actually named O and N in the backbone, which are usually hidden when ribbon is shown (in both Chimera and ChimeraX).
You’re almost there — all you have to do to get the element in either program is to omit the “at” symbol. In ChimeraX:
color O red targ a color N blue targ a
Also command “color byelement” colors all atoms by element, “color byhet” all atoms except carbons, both using the stereotyped element colors: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/colortables.html#element
Atom specification (by element or other things…) http://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html
I hope this helps, Elaine

Oh, I get it now. O and N refer to backbone atoms only, so to color
sidechains I would have to refer to each sidechain nitrogen and oxygen group specifically. Any shortcut for this in ChimeraX? Do I have to define a named selection?

Hi,
There used to be this handy command in Chimera to color oxygen atoms and
nitrogen atoms specific colors:
color @O red,a color @N blue,a
but I can't find the corresponding command in ChimeraX. Is there a way
to color all nitrogen atoms blue and all oxygen atoms red?
When I try what I think the equivalent command should be (I'm displaying
cartoon backbone with stick side chains):
color @O red target a color @N blue target a
it says 'Colored 1120 atoms' but none of the sidechains are colored
differently.
Thanks for the help
