I would like to restore the default panel colors.
I had recently installed Ubuntu 16.04 LTS and then Xfce 4.12. Xfce brought a dark task bar, I think.
I experimented with the 3 themes from Ubuntu (Adwaita, Ambience, Radiance) but I would like to go back to the Xfce default. Unfortunately, I don't know how to do that.
I tried to delete the contents of
~/.config/xfce4/xfconf/xfce-perchannel-xml/ (which was empty), and
~/.config/xfce4/panel didn't even exist. I also reinstalled Xfce, but Radiance is still showing up. Also, the icons appear to have changed.
The initial settings are not available as a theme. Is there another way to fix this?
