      A new Munker illusion, which I call confetti. All the dots in the background are the same color (RGB 250, 219, 172) but are perceived as four different colors. The differences are subtle, though, and depend on the size of the image when it's viewed. cc @AkiyoshiKitaokapic.twitter.com/vT6x64LLTy

      Magnificent! I have followed your idea and have made a similar image that yellow hearts appear to be different in color.pic.twitter.com/qLTqVebyvg

          Really nice! Your three-color version is more vivid than the four-color illusion because the gaps between the lines are constant width. I'd been experimenting with three-color illusions, but I found irresistable the idea of the four-color illusion.

          Is it just me or does the visibility of the red one depend on distance? Seems d=3w relationship. I.e. on mobile landscape image width 10cm, when within 30cm no red heart, past 30cm it suddenly appears ...

          Fascinating, even though I'm colour blind and understand little. Except I understand that Red & Blue make Purple, Blue & Green make Yellow, and, more surprisingly, Green & Black make Chocolate.

          There is no black. Orange is yellow plus red.

          Crazy -my percept of the background around the hearts changes with distance from the heart. On the left, background looks green but really there isn’t a background
