Daily Brain & Mind — Day 4 (Optical Illusion)
🧠 Lilac Chaser (The Pac-Man Disappearing Dot)
Stare fixedly at the black cross in the center for 15 seconds without blinking. What happens to the purple dots, and what color emerges in their place?
💬 Did the purple dots completely vanish for you? Did you see the green running dot? (Solution in first comment 👇)

💡 SCIENCE BEHIND THE ILLUSION:
Two brain phenomena occur simultaneously! 1) Troxler's fading: stationary peripheral stimuli fade from awareness. 2) Opponent-process theory: when lilac-sensing photoreceptors fatigue, your brain fills the moving gap with lilac's complementary color: a glowing green ball!
