Optical illusion tricks your brain into seeing COLOURS in black and white picture

This picture is in black and white! The optical illusion that tricks your brain into seeing monochrome as COLOR

  • Optical illusion appearing to show colours in a black-and-white picture goes viral
  • The internet has been divided after a picture of schoolgirls emerged online
  • The photograph shows schoolgirls wearing seemingly different-coloured shirts
  • On closer inspection, the girls are covered in red, blue, yellow, and green lines

A mind-boggling optical illusion has divided the internet after appearing to show a black-and-white picture of school girls in colour.

The photograph shows a group of young girls wearing seemingly different-coloured T-shirts as they smiled for the camera with a tortoise. 

But on closer inspection, the students are actually covered in streaks of red, blue, yellow, orange and green lines.

The snapshot is said to trick the brain into filling the blanks with the mind, giving an illusion of solid colours to appear where there are none.

Why do we see colour in black-and-white snap

The picture is said to trick the brain into filling the blanks with the mind, creating an optimal illusion of solid colours to appear where there are none.

‘This is a black and white photograph,’ Twitter user Lionel Page, from Sydney, said. 

‘Only the lines have colour. What you “see” is what your brain predicts the reality to be, given the imperfect information it gets.’ 

The picture was originally taken by Chuwa Francis but was later edited with a ‘colour illusion remix’ by Øyvind Kolås.

‘The image for the post is a visual/artistic experiment playing with simultaneous contrast resulting from other experiments these days,’ the post said. 

‘An over-saturated coloured grid overlaid on a grayscale image causes the grayscale cells to be perceived as having colour.’

The image has been retweeted more than 14,000 times on Twitter, and has since been doing the rounds online, including Reddit.

‘For me, the green and blue lines work the best and seamlessly blend into the background,’ one said.

Another said: ‘Red looks like a grid on a grey background.’

One explained: ‘I think it’s because the contrast between the red and dark coloured shirt is greater than that of any other colour combination in the picture. I know the human eye can see more shades of green than any other colour, but I’d imagine we see red more quickly because it implies danger (same colour as blood).’

Many people suggesting ‘squinting’ your eyes to see full colours.

‘Try squinting your eyes it goes full color its kinda crazy how much your brain fills in,’ one said.

Another said: ‘Squint or cross your eyes a little and the whole picture becomes colour. It’s brilliant and makes me want to rock up and down in a corner crying all at the same time.’

Meanwhile, some people said they didn’t see any illusion besides the black-and-white image with lines overlayed.

‘What I see is a black and white photograph with colored criss-crossed lines overlayed. This isn’t an optical illusion for me at all. Nothing special here,’ one said.

And another commented: ‘I only see a black & white photo with colored lines. What am I missing?’
