Hi Oleksiy, We cannot reproduce this problem on a Linux system either. So just these three commands produce white text for you: 2dlabels read your-labels-file 2dlabels change * bgColor 1,1,1,0.75 2dlabels change title visibility show If so, the only thing I can think of is that’s it’s a graphics driver bug — try upgrading your graphics driver and see if that makes a difference. Also, you should try the same commands on another machine if you can and see what color the title is. The final thing you should do is use Chimera’s bug-reporting mechanism (Help->Report A Bug) to submit a bug report. That will include a lot of information about the system you are using and may help us find the problem. —Eric Eric Pettersen UCSF Computer Graphics Lab

Hi Elaine, thank you a lot for looking at the problem. Sorry I forgot to attach the files, sending them now. I now suspect the problem is connected to my system. I updated Chimera to the 1.12, same story with default white colour for labels even if I open a brand new session.
Best wishes, Oleksiy

Hi Oleksiy, I could not reproduce this problem… although you didn’t attach files, I just put the label-file lines you gave into a text file (it was also necessary to add a tab before each line except for the first), then:
used 2D Labels dialog, File menu to read the label file entered the two 2dlabels commands given in your message
.. see attached image for result. I also attached the label file. Tested in 1.12 release and in current daily build, both on Mac, so it is still possible there is something different with your system. You could try the label file I attached to see if it makes any difference.
I hope this helps, Elaine ---------- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Dear community, I encountered a problem with 2D labels turning white disregards what colour presets I give.
The script reads title presets from a file (2dlabel path) and then display the title with these commnads:
2dlabels change * bgColor 1,1,1,0.75;
2dlabels change title visibility show
The 'title' label should appear as opaque black font as defined in the label file:
Label title (x,y): (0.18,0.5) text: u'Title' shown: False font size(s): 40 font style(s): bold font typeface(s): sans serif color(s): (0, 0, 0, 1)
But it appears in white. Bizarrely all other presets in the label file translate into the title appearance as they should except for the colour.
I run Chimera 1.11.12 (build 41280) on Unix. Script and label file are attached. Thank you. Oleksiy
