How to Trick Your Brain into Seeing This Black-and-White Photo in Full Color

This clip from the BBC Four Series Colour: The Spectrum of Science provides an awesome look at how easily our brains can be tricked when it comes to how we perceive the world around us.

In the beginning, the video shows a black-and-white photo of Dustanburgh Castle in the United Kingdom, followed by by a false color version of the exact same image.

If you end up staring at the blue dot in the middle of the picture long enough, your eyes will most likely see the image in full color once it reverses back to black-and-white.

Wondering how this is even possible? It works by manipulating the photoreceptors in your eyes so that they perceive specific colors, even if they’re not really there.

Pretty cool, huh?
