Courtesy of Truth, Lies, and Common Sense comes this optical illusion. Which square below, A or B, is a darker shade of gray?

Guess what? They’re the exact same color. See the proof. Or use the eyedropper in Photoshop or any other image-editing program that will give you values for the colors.
It’s absolutely true. Just checked in colorpic and saved it to photoshop.
A wonderful example of color (tints) and shape interacting with the human brain.
That’s just weird. And I just held a color strip against my forearm and Denzel Washington’s, and Bingo! We’re bros! We’re going out shamming tonight. He’s the man.
Leave it to me to argue, but it appears that the stripes themselves lend to the illusion.
