    Here's a second confetti illusion. All the dots in the background are the same color (RGB 248, 205, 172) but are perceived as four different colors. Like all Munker illusions, this is affected by image size. If the illusion isn’t clearly apparent, try shrinking the image.pic.twitter.com/VXjtbIovhm

        Is this really an illusion, or is it simple color mixing, ala four color printing or RGB mixing? Your monitor is doing this right now.

        There must be an issue with image compression from Twitter. The original image was created by pasting the same color in all dots simultaneously, and I confirmed the values via the Apple digital color meter. I'd be happy to email you the png image!

        Glen-- Not really. I did get into Magic Eye images for a while, though. :-)
