Optical Illusion Makes You See Colors In These Black And White Pictures

Most people see colors in these photos, even though they are actually black and white pictures. Here's the explanation.

Øyvind Kolås is a digital media artist and software developer who figured out a way to trick our brains into seeing colors, even though in these pictures, only the lines have colors.

Your brain is basically just 'filling in the gaps', by receiving indications from the colored lines and predicting the fully colored picture.

Øyvind Kolås has tried this experiment with multiple photos and patterns and named it the 'color assimilation grid illusion'. In his experiment, he tried laying various patterns over grayscale photos. While grids appear to have the best effect on most people, dots and lines also create the illusion similarly.

"I came up with this illusion by experimenting with different patterns-and recently having worked on improvements for the saturation operation and being inspired by David Novick's Munker illusions," Kolås shares.

In this video, only the grid is colorful, the rest is grayscale. Can you see colors in it?
