I consider myself pretty cluey, but this video has me scratching my head. In it we see tiles underneath a shadow, but all is not what it seems.

Our attention is drawn to tiles that appear to be different colors, but one is taken away from the shade we see that they’re actually the same. I understand that shadows will always darken what’s underneath, but this is ridiculous.

I’m still trying to work this out, and the more I watch it the less sense it makes. Surely this is camera trickery or perhaps the work of demons! It certainly defies my logic!
