[chimerax-users] Re: getting HEX code from molecule

Hi Donna, I added "info atomcolor" and "info rescolor" commands to report colors using hex codes in tomorrow's ChimeraX daily build (dated September 2, 2023). For example,

info rescolor /A:16 #1/A:16 color #d2b48c

info atomcolor /A:16 #1/A:16@N color #3050f8 #1/A:16@CA color #d2b48c #1/A:16@C color #d2b48c #1/A:16@O color #ff0d0d #1/A:16@CB color #d2b48c #1/A:16@OG color #ff0d0d

Hello Donna, Not a command, but you can do it by clicking various color wells, which will call up your system color editor. The system color editor should have some way of showing the hex code of the color. I say "system color editor" because it just uses the built-in color editor of your computer system, so it will be different on Mac vs. Windows vs. Linux.

E.g. For model color you click the color well (small square with color in it) in the Models panel.

For atom color: You would do it by selecting the atom (Ctrl-click in graphics window), then opening the Selection Inspector by clicking the green magnifying glass icon in the Home tab of the Toolbar, or by choosing menu: Actions... Inspect. In that tool, Inspect: Atoms, click the "Color" color well.

For ribbon (cartoon) color: Ctrl-click to select part of ribbon, open the Selection Inspector as above, Inspect: Residues and use the "Cartoon color" color well instead.

I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hello, I was wondering if there's a command that would give me the HEX code of a particular atomspec. Using the "pick from screen" option in the color editor is somewhat helpful samples the colors that are the results of shadows so I can't really the exact color.
