Hello, my name is Javier and I am a Bioinformatics PhD student in Dundee. I am using UCSF Chimera v1.14 and I am trying to select residues according to the colour they are coloured in, using the following command for blue-coloured residues for example: "sel @/color=blue". This works just fine, however, I struggle when using other colours such as "medium blue" or "dark green".  "sel @/color=darkgreen" does not work. It looks like all colours with a single word name work fine, but 2-word name colours do not. Moreover, I can colour residues using RGB codes, such as "col #da70d6 sel" to colour selected residues in orchid. Nevertheless, "sel @/color=#da70d6" does not work. "sel @/color=orchid" works, though. So, is there a way that I can use two-word named colours when selecting by colours, and also, use RGB codes or other colouring codes to select coloured residues?

Many thanks,
