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 often aren’t as similar as we like to imagine. # Credits Andrew Steele Tom Fuller Maya Evans Tran Nguyen
