My favourite optical illusion

Can you trick your brain into seeing a black and white image…in colour? This is definitely my favourite optical illusion—it’s mind-bendingly effective but infuriatingly ephemeral, vanishing as soon as you try to look straight at it—and a fantastic illustration of how our eyes and brain together conspire so that what we see and reality aren’t as synonymous as we like to think. # Credits Andrew Steele Tom Fuller Maya Evans
