Revert Grasshopper background to default

Hi all,

Recently I’ve been working with some templates provided by a school instructor and since then all my GH backgrounds look plain white

How can you revert it back to the default background?

Thanks in advance

See if wombat’s Canvas Color still works:

As I recall, one can delete the grasshopper_gui.xml file to reset the Grasshopper appearance settings (maybe save a copy first, and remember to close Rhino):
