Here is fun optical illusion where your eyes play a trick on you!
If you look at the center, the dots look purple—but check your peripheral vision and they start turning blue (or even disappearing!).
This is a “simultaneous contrast” illusion. Because the background is blue, your brain “over-corrects” the dot you’re focusing on to make it pop, while your side-vision loses the battle.
