Colorful Optical Illusion

I like optical illusions. When I first saw the Big Spanish Castle (via BoingBoing) I was really impressed because I’ve never seen this kind of illusion before. So I created my own versions using pictures I took about a year ago.

All you have to do is:

  1. Make sure the pictures change when you click them (i.e. JavaScript needs to be enabled).
  2. You have to see the color picture to begin, not the black and white one. Click to get the color picture should you see the black and white one.
  3. Stare at the black dot for about 30 seconds.
  4. Don’t move you head or eyes!
  5. Click a picture to change to the black and white version.
  6. Instead of the black and white version you see a colored version with natural colors. But this is just an illusion!

John (the “Spanish Castle guy”) created a list of many optical illusions like the one above. (This is where most of my traffic comes from at the moment.)

    Be sure not to blink or move your eyes while staring at the dot. Then it should work.

    I’ve reworked the original images and added two more. Now they are more like the Spanish Castle. Tell me which ones work (best) now. I’m curious (and to tired to test them myself)!

    John has a tutorial on his blog. It’s focused on Photoshop though many tools should work. For example Gimp. In step 4 you have to use the mode “Value” instead and change the colors afterwards until they look like in the picture used on the tutorial (you can use “Hue-Saturation” for this). Actually you could use the picture in the tutorial and make it look like the final version to learn how to modify the images with your graphics editor of choice.
