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
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

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.

I think your way of design is new!

WOW! When was this illusion discovered? It’s fantastic!
-
Munker published his work in 1970 on the illusion that now bears his name. My efforts are just variations on the results of Munker and
@AkiyoshiKitaoka. I think, though, that my "confetti" version of the the Munker illusion is novel. -
But this is hardly an illusion - the perceived colours are there in form of individual RGB channels, at certain distance (and or poor eye sight) your see the composite colour as they mix (akin to how basic colour LCD or CRT works). Ok, perhaps an illusion as exact colours are new

Two things I noticed, on closer inspection; ① The hue of the green bands change over six of the circles, and the relative sizes of the blue/purple bands change over three of them. I am assuming, not part of the illusion, but accident during CnP?
-
Correct. The green differences are due to copy-paste, and the minor changes in the size of the bands is due to the limits of my abilities to get good alignment. Here's a version with most of this fixed. I didn't anticipate the original image getting 10k likes!pic.twitter.com/GykAQraDJf

When I take a screen grab of the image and open it in GIMP, the colour picker shows them as being different. Is this an artefact of copying the image?
-
Must be an artifact. The dots were colored simultaneously, and my color picker on the png image shows the values to be correspondingly identical.

Some wierd stuff with the color bars, like someone tried to "enhance" things.pic.twitter.com/iA4vLn8POY

The differences in the green stripes were due to a copy-paste error. Here's a version with this fixed. I didn't anticipate the original image getting 10k likes!pic.twitter.com/MARe7lockt

the background is not the same for each dot.

I'm not sure what you mean. The dots are exactly the same color, and the background stripes are all the same. The only differences between the dots are the foreground stripes.
