"Illusions are often used especially in art by, in the words of a more contemporary artist, to demonstrate the fragility of our senses. This is complete rubbish. The senses aren't fragile, if there were we wouldn't be here. Instead color tells us something completely different, that the brain didn't actually evolve to see the world the way it is - we can't. Instead, the brain evolved to see the world the way it was useful to see in the past and how we see is by continually redefining normality."

So basically the visual cortex of our brains have evolved a sort of plasticity in it's mechanisms so that we can normalize color perturbations in our environment (and in attempt to restore it back to what we're familiar with we end up with an "optical illusion")
Here's something thats's related and interesting to think about ...
The PET brain scans of a person who's been blind all his life, but experiences color-synesthesia, shows activity in the color-sensitive areas of the visual cortex ...
