Ted Talks

I had the same question as Mario after watching the video. Why would color change based on background be associated with the evolution of our world and reality? That doesn't really make any sense to me, so I kind of feel like that is just a theory to think about. I had to come home and watch the video again because I felt like he was tricking us on some of the illusions, but I couldn't find any trickery, so now I just think it is odd that our brains retain color information and impose it on other objects. What in the information, besides the fact that it is light, makes it stay in our vision, like with the green and red desert scenes. Optical illusions are fun, but my brain gets tired of them quickly.
