Technically we're all seeing in XYZ , which can then be mapped onto RGB. Mostly.
If an optical illusion tells you "you're going to see a colour that doesn't exist!", It's because by staring at a colour for long exhausts some of the detectors, and then the remaining detectors will send a colour in XYZ space that doesn't properly map to RGB.

No. Colour spaces are complicated and make me cry.
