You can learn to see the impossible colors

Have you ever had to see yellow and blue tint, but not green? Probably not, since the principles of perception and color processing in the human brain does not allow people to see some shades.

When human perception of color are three different types of receptors, each of which is responsible for the recognition of certain length of light waves. Color receptors called cones, and depending on the sensitivity of the cones peaks occur in red, blue, or green portions of the spectrum.

The wavelengths sensed cones intersect, and color perception brain processes, not all of the reaction flasks, and only the difference between the reactions of different receptor species in the same color. Due to the nature of functioning cones human brain can not perceive the combination of two so-called opponentnyh colors - red and green, blue and yellow, white and black.

In 1982 the staff of Stanford University and Thomas Hewitt Crane Pyantanida an experiment, in which, with the help of special equipment could cause the test to see non-existent color.

One eye volunteer saw the green screen, and the other - red, in normal circumstances, the brain "blends" the colors, bringing people see brown, but the researchers were able to prevent this, and the participants opened a new "red-green" color that first one of them, including an experienced artist, not seen.





Despite the fair criticism of the methods of the experiment, many scholars suggest that under certain conditions a person is able to see colors, which he had never seen before. To test this for yourself, try to look intently at the two plus on picture below. See the "forbidden" color right the first time will not all, but in some cases there are shades, which you had never seen.
