Green Heart Optical Illusion

Stare steadily at the dot in the heart for 30 seconds, then look at a piece of white paper. A faint Red heart surrounded by a bluish outline should mysteriously appear on the paper.
Green Heart Optical Illusion
This is called an aftereffect. Staring at the heart overstimulates your eyes' photoreceptors, which are what absorb the light that stimulates vision. So even after you look away from the image, your brain is still receiving messages about it. What you end up seeing are called complementary colors. Red and blue are complementary colors of green and yellow.

    That's the basic learnt at school about art.. the three basic color, red, blue & yellow..
    some other color-pairings which compliment to each other:
    black & white
    green & red
    blue & yellow

    it's like the negatives in the old camera films (nowadays it's hard to find film-cameras, mostly digital)
