Out of all the color afterimage photos, this one stood out the most to me. I genuinely thought that the picture on this slide was colored, and was mistakenly put in instead of the black and white one, until I blinked. It is quite fascinating how our brain, or rather, the color receptors in our eyes show the complementary color in the afterimage, which lets us create unique optical illusions like these "colored" photos.

I completely agree with what tlswoo said. The effects are truly imaging, and in cognitive science, I learned this and it is called the opponent-process theory. Basically, it states that the human visual system interprets information about color by processing signals from cone cells and rod cells in an antagonistic manner. Then I wonder why is it the case and can we borrow some of those ideas in computer graphics?
