Ok, I stand corrected.
Tried it with my IR tile and even if I pass the green pointer trough a pair of IR glasses it did quench the IR tile, so ya, it seems green also works.
Just tested this out with a green laser. It looks like green also works yeah. My laser pointer doesn't have an IR filter so I wasn't able to test if it's just the IR/green that "de-charges" the GITD surface.
