[chimerax-users] Recall the color code from a previously defined color

Dear all, I checked through old archive mails, I may iterate this question again about the color code. Is there a command/option to retrieve the color codes in the Reply log from previously used in the ChimeraX session? I saved my session when I defined the Grey scale for one of my surface model in the palette GUI… When I clicked on the other structure I want to know what color I previously used, the RGB code changed to grey as well… Would be a way to retrieve the color code in the Log I defined previously? Thanks, Hong
