When I first looked at the black and white lines just now, I already saw a faint green and magenta glow in them. I hadn't even looked at the colored images yet.
Then I remembered that several months ago I tried this. Could it have possibly lasted that long?
- Houshalter 12y agoI also experienced this and saw the image a few months ago. That the effect lasts that long is sort of unsettling.
- cypherpunks01 12y agoYep, wikipedia cites a 1975 study "Extremely long-term persistence of the McCollough effect" in saying that the effect can last up to three months in some cases, after prolonged exposure.

- neotek 12y agoI tried this several years ago and still see green and pink when I look at the black and white lines. The green in particular is quite strong.
- deciplex 12y agoSame here, though the effect is not as strong as it used to be. At first glance I see the colors, but then they are gone and all I see is the black and white stripes.
