A mind-bending optical illusion recently shared on Twitter has gone viral – and it’s making people question their own eyes. The ‘Confetti’ illusion was created by David Novick, a computer and information science engineer. It shows 12 circles with multi-coloured horizontal stripes.
Take a quick glance at the picture, and the circles will appear green, red and purple. Look a little more carefully, and you will realise that all the 12 circles are the same light brown colour.
“A three-color confetti illusion with spheres, which appear to be yellowish, reddish, and purpleish but in fact have exactly the same light-brown base color,” wrote Mr Novick while sharing the optical illusion on Twitter. He added that shrinking the image would result in an increase in the effect.
