#1. Do you see a chessboard with black and white squares? The gray halves of both black and white squares are actually the same color.
The color gray can be perceived as black or white depending on the color next to it.
#2. The blue and green spirals are actually the same color — green. There’s no blue color in this image.
#3. The brown and orange squares in the center of the top-facing side of these two cubes are actually the same color.
#5. Look carefully at the chessboard. What color are squares A and B?
A might look black and B might seem white, but they’re actually the same color. Watch below.
#6. The bottom part of this shape seems lighter, but if you cover the horizontal divide between the two shapes you’ll be amazed.
#7. If you stare at the cross in the center of this image, it appears a green dot is replacing the violet spots. But it’s not there.
And if you focus on the center cross, the spots will disappear altogether.
