Red is complimentary to cyan.

If the cyan were switched with yellow, the can would appear blue.

Also, it's not our brains creating the red, it's our eyes. They get exhausted of seeing the cyan and replace it with red.

Huh, it shows up as black to me.

It depends on the size you are viewing it at. This works well on small screens but less well on large screens

So if the can shown wasn't Coke, but Sprite, it would still appear red? Or is it a mix of both? The eyes are confused and the brain fills in? Like when seeing pink as mentioned elsewhere.

Your brain isn't filling in anything. Your blue and green receptors get oversaturated by the cyan, which causes your red receptors to be more sensitive to the white light than the other two, which is why it appears red. The effect happens in your eye, not in your brain.
