Set specefic GTK theme and icons to xfce4-panel
Ok the title is very descriptive and what I want is to be able to set a theme for the panel different from the system theme because light icon themes rarely match in colors with the background in any theme, so setting the same GTK (WhiteSur Light Solid with WhiteSur Icons) but at its black version is a perfect solution. Same as any other decent theme I have tested... But I don't want to change the system theme. Just the overall panel theme.
