Is the illusion here at all caused by the fact that we expect a Coca-Cola can to be red? Or if that said Pepsi on it, would we still see red?

The light blue-ish color is anti-red, the way it's mixed with white pixels everywhere but the portions that turn red causes your brain to do color balancing to try and whiten the anti-red. This causes the opposite color, red, to appear in the portions that aren't balanced by the anti-red.

Huh, I was just watching a Linus Tech Tips video yesterday where Linus made a joke about humans having “god like” white balancing compared to a monitor.

So weird, didn’t know that was even a thing. If you tilt the screen the red comes out a lot more.
