Hi Jason,
thanks for the reply.
Your method works well for the single color background.
For the gradient BG however the problem still remains:
PyMOL>set bg_gradient, 1
PyMOL>get bg_rgb_top
-> this returns '00004d', which seems to be the hex-value.

However when I try to set the bg_rgb_top/bottom value (regardless if I use hex 
or rgb-list) I still get an endless output of:
Setting-Error: type read mismatch (color) 663
Setting-Error: type read mismatch (color) 663
Setting-Error: type read mismatch (color) 663
Setting-Error: type read mismatch (color) 663
Setting-Error: type read mismatch (color) 663
...

This message keeps flooding the output shell until I close the program. I guess 
this is rather a bug than intended?

Best,
Nils

Hi Nils,
 
We've updated how PyMOL stores colors in sessions. You can try,
 
cmd.get_color_tuple(cmd.get("bg_rgb"))
 
or if you need it as a list:
 
list(cmd.get_color_tuple(cmd.get("bg_rgb")))
 
Cheers,

Hello,
 
I recently installed PyMOL 1.6 on my Debian machine. I have noticed that the 
description of the background colors has somehow changed. The command "get 
bg_color" returns [R,G,B] values in all previous versions, while since 1.6 it 
only returns values  like "black" (which messes up some of my plugins and 
scripts). I'm not sure if this some kind of bug or a new way of handling 
colors...
When I try to set the background gradient colors (set bg_rgb_top/bottom) I get 
an endless output of "Setting-Error: type read mismatch (color) 664" - I have 
to kill and restart the program to get rid of the message. Same happens with my 
scripts using cmd...
Can someone confirm these problems? Perhaps I'm doing something wrong here.
 
Thanks in advance,
Nils
