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.

Thanks,

Done.

I added "info atomcolor" and "info rescolor" commands to report colors using hex codes. 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

I assume "rescolor" means residue cartoon color and will only apply to biopolymer residues?  There is also a per-residue ring-fill color, but ring fill is not used that often.

Yes rescolor reports cartoon color. All residues even non-polymers have a ribbon color that can be queried, although it is not used for non-polymers. I did not add a command to report ring color.
