As unbelievable as it may seem, the squares marked A and B are the EXACT same shade of gray.
Credit to Airtight Interactive for mentioning it. If you’d like the full explanation, you can find it here. In addition, more illusions can be found care of Edward Adelson.

That optical illusion thingy is cool / insane / frightening all at the same time. Makes me question whether what I see with my own eyes is real or not.
Thanks for sharing it!
