RE: Progress bar colours

Thank you for your reply. Can't the programme just change the relevant aspects of the theme, to change the way the progress bar is drawn under certain circumstances?

Depending on your Gtk theme, progress bars can be animated pixbufs, so I
doubt you can change the color programmatically.

If I had to do this, I would create a custom widget containing a drawing
