Ok, so when I setup my theme the first time I was using HUD Machine Green and I was able to change the default color scheme of Windows 10 to match. I now can't do that anymore, it doesn't change anything now and none of this was an issue before installing a theme from here. I've tried RestoreDefaultColors assuming that's what was stopping me, but that doesn't seem to be changing anything either. Am I missing a registry edit or something else?

I'm using HUD Machine Launch right now if that helps at all, I just want to change the default colors to match so I don't randomly get green in some system window while the rest of the computer is orange and black.
