Thanks Elaine and Guillaume. info atomcolor was exactly what I was after!

For example, I had a density map #2: info models #2 attribute color ... giving in the Log: info models #2 attribute color model id #2 type Volume color 178,178,178,255 model id #2.1 type VolumeSurface color 225,178,250,255 The "Volume" one is if the map were shown as a semitransparent cloud, whereas the "VolumeSurface" one is the isosurface color. If you have some kind of multicoloring (by electrostatic potential etc.) this will not give it, it only gives the single-color assignment. Elaine

Thanks for the reminder! Yes, you can also use "info atomcolor" and "info rescolor" as mentioned in this earlier post:

... and in the documentation: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/info.html> <https://rbvi.ucsf.edu/chimerax/docs/user/commands/info.html>>
That doesn't include nonatomic models, however.

Hi Elaine,
Is there a command to report the color of a selection in the log? A quick search in the help pages didn't turn up anything. Thank you,
GuillaumeFrom: Elaine Meng via ChimeraX-users <chimerax-users@cgl.ucsf.edu <mailto:chimerax-users@cgl.ucsf.edu>> Sent: Friday, June 13, 2025 5:27:25 PM To: Walshe, James Cc: chimerax-users@cgl.ucsf.edu <mailto:chimerax-users@cgl.ucsf.edu> Subject: [chimerax-users] Re: Get model chain color Hi James, There are several dialogs with a square "color well" showing the current color of something, and you can just click the color well to bring up the system color editor. In the color editor (system-dependent as to how exactly it looks) there is generally some way to see the hex code or RGBA values of the color.
If it's the whole-model color, you can click the color well in the Models list. Or if it is some specific residue's ribbon segment or specific atom, you can select that ribbon segment or atom, and then open the Selection Inspector and inspect that kind of item (Atoms, Residues, etc.) properties to show the corresponding color well. You can open the Selection Inspector with menu: Actions... Inspect, or click the green magnifying glass icon in the Home toolbar which is normally across the top of the window.
I'm on a Mac so when I click a color well I get something like what is shown in the attached screenshot.
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Resource for Biocomputing, Visualization, and Informatics Department of Pharmaceutical Chemistry University of California, San Francisco

Hi All, Is there an easy way to get the color code for a model? Or a specific chain of that model? Let’s say I really like the default colors a model is loaded with and I want to find the exact hexa color code for each chain? Thanks!
