[Coco] Inverting VDG text screen on a CoCo 1/2?

I wrote a program to go through the 6847 T1 VDG text modes, which includes lowercase, changing the border, and inverting the screen.
I’ve seen programs on the CoCo (like GRABBER) that invert/reverse the screen in software, but the bits to do that on the T1 don’t seem to do anything on the 6847.
Does anyone know of a reference that would show me how to do this? Thanks, much!
