We are using the system color editor.  It is not a part of the ChimeraX code or anything we would be modifying, although happy to take praise :-).  

However, if you're on a Mac and you mean the hex code, it is shown in the "RGB sliders" pane of the color editor.  You can still use the picker to pick what you want, and then switch to that pane.  See attached screenshot.

I hope this helps,

Hi,

I love the color editor in ChimeraX, it is much nicer than the one in Chimera and is super useful!

One minor suggestion - would it be possible to add a dynamically updated label showing in the editor the current color code? This sometimes shows up in the log but not always, and it is useful to have easily copy-able for use in scripts and aliases.

Cheers
