The McCollough Effect - seemingly a very long-lasting afterimage effect, although it appears to have a quite different mechanism.

The McCollough effect at Wikipedia.

  • *shakes fist at Hank* Great, one of my old acid haunts has returned! For the love of... *smashes monitor*
  • Warning: may cause irritation & damage to monitor
  • changed by the consumption of coffee and other psychoactive drugs oooooooh, teh colors!!!
  • That's really interesting, thanks!
  • Didn't happen for me, but my binocular vision isn't normal. I cant see 3-D movies, either.
  • I just noticed something about this effect. The effect for me was slight: a yellowish-green in the horizontal field but no effect at all in the vertical field. The interesting part is that if I move my head closer to the monitor, or further away, it disappears completely. If I return to the distance where I viewed the colour fields, the green haze returns.
  • So are you an extrovert or an introvert
  • whoa, that is cool. especially in how long the effect lasts.
  • I just got a headache. Thanks a lot.
