An eye-boggling image has taken the internet by storm. A black and white picture seems coloured to most of the users.
The photo shows a group of young girls posing with a small tortoise. Ever since it surfaced online, the picture has gone viral. The picture is black and white, except for the fact that it is within a coloured grid. The reason why it appears to be a coloured image is because of the grid that is embedded within the picture. The picture is just another brilliant example of optical illusion. Here's the picture which was captioned:
"What you “see” is what your brain predicts the reality to be, given the imperfect information it gets."
This optical illusion tricks the human brain to spot a coloured image. One needs to look closely to realize that it's actually a black and white image. The 'hard-to-believe' image was shared on the micro-blogging site by Lionel Page, an economist at the UTS Economics on July 27. As soon as he uploaded the image, Twitterverse was set in motion and long discussions followed.
Users of all sorts tried to figure a way out of this visual trap. Read some of the reactions here:
Just in case, if you are wondering, the picture has undergone a visual experiment and is digitally modified. As per reports, the visual artist and software developer who developed it described the technique as a ‘colour assimilation grid illusion’. He said the image achieves the effect by simply laying a grid of selectively coloured lines over the originally black-and-white image.
