Optical illusion: do you see a pretty woman on a white background?

A new optical illusion has appeared on the Internet. On one side of the image is visible the negative face of a woman, and on the other - a white background. Here,as you can see the illusion:
- Look at the white dot on the woman’s nose for 15 seconds.
- After that, move your gaze to the white background on the right.
- At some point you will see how the negative turns into a color photo of a pretty young woman with dark hair.

Optical illusion: post image

Optical illusion is based on the phenomenon of "post image". Eye photoreceptors determine colors and encode them so that it is understandable to our brain.

In peoplethree color channels: grayscale, red and green, as well as blue and yellow, which allow us to encode colors in any environment.

When we look at a certain color, the cells of the corresponding color channel become more active.However, after some time, the cells get tired and their activity decreases.

Color perception

For example, if you look at something yellow for a long time, you stimulate cells that are susceptible to yellow, in the yellow and blue color channel.

When you then look at a uniform background, for example, on a gray wall, the cells are not at rest. The yellow code is weakened, and the code for the opposite color becomes stronger, and you see blue.

In our illusionblue receptor cells get tired and their activity decreases, which stimulates the opposite color - yellow.

This allows us to see a more natural skin color and the opposite image.
