Would you believe that the blue and the green in this image are actually the same color? It's true! I verified it myself by opening the image in Photoshop and sampling the blue and green... they both have an RGB value of 0, 255, 150 (Or in other words, mostly green and some blue). According to this site "The reason they look [like] different colors is because our brain judges the color of an object by comparing it to surrounding colors. In this case, the stripes are not continuous as they appear at first glance. The orange stripes don't go through the 'blue' spiral, and the magenta ones don’t go through the 'green' one."
The original seems to be by Akiyoshi Kitaoka. It blows my mind!
