Cool idea, here's what it looks like.
Hands down the most startling optical illusion I can remember seeing.
Thanks for providing that image. This is a very powerful effect.
For instance, I have to focus on it very hard to temporarily not see it.
Can anyone NOT see this effect easily? Or is it fully universal?
I can see the colors changing in the modified image, however, the effect seems to be a lot more subtle for me than for other people.
I was very confused by the first image, because the tiles others are identifying as yellow on the right cube look gray to me; that is, I don't see any yellow boxes on the right cube; I had to look at the modified image just to know what boxes to compare. I've never been diagnosed as colorblind, but have on rare occasions argued with people about the color of items that have a similar gray appearance. Anyone care to hazard a guess what's going on here?
Is it possible that you are super-un-colorblind? http://en.wikipedia.org/wiki/Tetrachromacy
If you turn out to be humanity's third identified tetrochromat, I want 500 karma.
Color vision deficiency? Variant cone cell pigmentation in your X-chromosome(s)? I imagine running some color vision tests might be informative.
Interesting. I can "focus on" the four gray (blue) tiles on the left cube and see them as gray, but I can't see the yellow tiles on the right as anything but yellow just by thinking.
Any color blind people look at this? I blocked off the surrounding color with a pair of envelopes, and the line then looks the same color, but it seems to be darker on the left side (yellow-tinted cube) than on the rest of the line. Edited for clearness.
Neat - when I look at it up close, I see the 'line's color changing' effect Silas mentioned. But when I back off, I instead see a grey line connecting the squares, including a ghost image of the line overwriting part of the colored square.
