Hi;
I have modified the MOI environment in terms of background color to fit my need. I have one question, how can I modify the viewport frames (color and thickness), so It could have less contrast with the background color. I understand that the UI environment can be modified with editing of htm files located in "UI" folder. I don't know which file or section of the file I have to modify to get this change.

Thank you for your help!
