A software developer recently published a visual experiment that makes your mind find colors in black and white images and the internet is amazed by the bizarre illusion.
An odd, fascinating optical illusion tricks you into seeing colored pictures but if you look closer or focus with your eyes half shut, you will realize that the pictures are actually black and white!
Recently an artist and software developer, Øyvind Kolås published the visual experiment that makes you look at colors in black and white photos. The mind-boggling photographs went viral all over the internet pretty soon.

The experiment is based on ‘color assimilation grid illusion’. The trick behind the photo is that the colored grid sort of gives your brain a clue on what the rest of the photo should be colored like and it automatically applies color.
Øyvind explained as to what actually tricked our minds into seeing color in black and white images. “An over-saturated colored grid overlaid on a grayscale image causes the grayscale cells to be perceived as having color,” he said.
The developer further told us that it is not just grids that can cause our mind to find color in grayscale images. Dots and lines can work equally well in creating magic. In fact, the technique of using dots to make an area look color has been used in comics for quite some time.

Works better at smaller scale; and when looking at other parts of image. pic.twitter.com/7UwkriMy8a— ̐🐿ṕ̒ͪͬͯ̐̐̐̐̐̚ȉ̓̈̅̄̓̀p͒̍̚p̏͗̊̔͒̐̐í͆͆̓ͮ̔ͮ͆n̒͐̀͆ (@hodefoting) July 28, 2019
According to vision scientist Bart Anderson from the University of Sydney, our brain compresses visual information when we look at things, giving us an overall impression of what's there if we don't take the time to examine objects closely.
