Friend of mine emailed me this cool picture! You may ask what’s so cool about it, thats what logically follows. I suggest you try figuring out yourself what is the illusion here, but if you are lazy continue reading this post :) This illusion is another example of this. Believe it or not, all diamonds in this picture are of the same color! It’s true! Jump inside this post to see the proof. After you’ve finished, check another few examples here: candy stripes, which color is darker, gray squares… and then take the color blindness test! More similar illusions can be found in color adapting category.
