One of the best optical tricks

I assure you, it's a genuine optical trick. It's not a screamer (only the image colors change), and it's not a cheap trick.

If you want to know how it works, highlight the rest of the paragraph: When a color changes while we are focused on something, for a while we see the inverse color of the one we were watching instead of the new one.

The mechanism behind this is similar to this one.
