A MIND-BOGGLING optical illusion has gone viral where all isn’t what it seems.
It features what appears to be a colourful photograph with school girls posing for a picture.
But actually this photograph has no colour at all.
In fact this is a black and white image which uses a method to trick your brain.
Once you find out how it is done, the colour begins draining away.
For optical illusion is created by printing dotted lines over the children.
The picture surfaced on Reddit before going viral.
One user of the social media site said: “For me, the green and blue lines work the best and seamlessly blend into the background.
“Red looks like a grid on a grey background.”
Another said: “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).”
