これ、ほんとは全部おなじ色！「ムンカー錯視」脳がだまされる“錯視”の不思議David Novick @NovickProf 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 @AkiyoshiKitaoka pic.twitter.com/vT6x64LLTy
