TED Talk: Optical Illusions
I thought it was interesting that how we see can be based so greatly off of the context of the background or environment. Lotto also brought up an interesting point that the way we do see has been based off millions of years of evolution. SO what makes us see different colors when they're against a black background opposed to a white background and what purpose has it served in the past for it to affect our vision today?

I thought that the image of the tiger was a good example of how color perception helps in survival. When the image was just achromatic, the tiger was invisible, but when he showed the same image with the hues, you could see the tiger easily.
