This is one of the neatest illusions I've ever seen. Rewind the clip to confirm a black & white image. Very cool.
EDIT: Try darting your eyes from the dot to one side of the picture when the rainbow appears and back to the dot. You'll see the color wash out to black and white, then become colored again when your eyes refocus on the dot. |

After listening to that Paris Hilton thing I just couldn't take this one seriously. I was expecting another gag. |

If you stare at a color or set of colors long enough (your eyes have to stay focused on the same spot for this to work, that's why they tell you to focus on the dot), it forms a sort of temporary "imprint" on your retinas. Then when you stare at a white surface, you "see" the object or imprint, but as a "negative." So if you stare at a blue blob next to a purple square for 30 seconds and then stare at a white wall, you will "see" an orange blob next to a yellow square. This illusion works on the same principle, only the negative you're given to stare at is adjusted for the fact that you will be looking at shades of black and white instead of just a white surface. That's also why, as Oni-Neko noted, it no longer works if you take your focus off the dot after the picture pops up, but will work again once you re-focus on the dot -- you are, in essence, dis-aligning and re-aligning the the color portion that is "imprinted" on your retinas with the black-and-white base picture. This is also the same principle that quickly causes eye fatigue when reading a web page with a black or very dark background and white or very light-colored text. |
