List of saved named colors is missed in new gcolor3, but exists in previous gcolor2
Just compared two versions of gcolor side by side:
gcolor2 version has list of saved named colors (not user-defined, but known).
Some users can't/don't remember
blue4 and so on color names.
I hope you will add missed functionality to
gcolor3. It's expected as you create substitution for obsolete application.
