Wowza! File this under things you probably didn't know! It's called the McCollough Effect and it can change the way your brain looks at color.

As the video explains there are certain times were we get a song or image stuck in our head. While most of the time it's just an annoyance it sometimes can stay so long that it can do harm to our brains. Most of the time it's images but scientists have developed a series of two images that if we stare at them long enough our brain will actually see the colors as the inverse of one another.

Most of us will see this inverse for a brief period however, the McCollough effect can stick around for up to three months!

The video won't allow you to stare at the images that long and we don't recommend doing it.
