I also tried this but wanted to switch back to the default, and I was able to get the default colors on everything except the viewport background for some reason… colorscheme doesn’t restore it, and manually going to File > Properties > Appearance > Colors > Viewport Colors > Background and changing the color doesn’t do anything… changing the other colors has an immediate effect (like major grid lines and so on) but the background specifically does not want to change… help!
I have uninstalled Rhino and downloaded again with a brand new installer but the color stays the same, I really don’t understand why the color persists.
