Your Eyes Are Confused
Thanks to Gizmodo, I'm completely blown away by the following optical illusion. Yes, it's a bit nausea inducing. But what's really insane is that ... the blue and green in the below image are the same color.
Here's the mildly convincing reason why:
The reason why we are perceiving one color as different colors is because of the other colors surrounding the stripes. Each eye has six to seven million cones, which are concentrated in a central yellow spot known as the macula (I recently got mine lasered to fix some leaking blood vessels). These cones measure color in different wavelengths, overlapping in some of them. Our brain then compares those signals in an antagonistic manner, measuring differences in wavelengths between them. When some colors are combined, the brain can't process the info from the cones correctly and we simply get confused.
Yep, we see this because our eyes are confused. That's a bit crazy.
