Perhaps people see colors differently Bashny.Net

Anyone with normal vision would agree that the blood red color, such as strawberries or the planet Mars. But could it be that what we call "red" is for another, for example, "blue"? Until recently, any scientist would you have said that people with normal vision can see all the colors equally.

How we see color? The brain processes the light that hits the cells of the eye, and our perception of the color of light is connected with the universal emotional response. However, recent experiments have shown that perhaps we perceive colors differently.

In other words, you have the blood of the color that the other person will call blue and your blue sky for someone to be red. But our individual perception will not affect it, what emotions will cause the color of blood and the sky.

This phenomenon has been demonstrated in experiments on squirrel monkeys in which, as in most mammals, color blindness and two types of cones: those that are sensitive to green and those that are sensitive to blue. That is for them red and green wavelengths of light looks neutral and they can not see the red and green dots on a gray background.



Scientists from the University of Washington introduced the monkeys the virus which allowed them to see the red and green and yellow. Thereafter monkeys were able to new information, despite the fact that their brains are genetically programmed to, receive signals to red.

Research on monkeys, conducted in 2009 showed that the perception of the wavelength of light is not predetermined. All this led scientists to think that the color - it's a personal feeling. When we are born, our neurons do not respond to color in a predetermined manner, and we have developed a unique color perception.

However, despite the fact that we see colors differently, our emotional response to the same color is universal. No matter what you see, looking at the clear sky, it is a short wavelength of light, which we call the "blue" color, a soothing effect on us, and long, that is, yellow, orange, and red stimulate us. As the scientists explain, our reaction to color appeared to all living organisms determined by the cycle of day and night. So the dominance of blue night explains why at this time we feel the most tired, and the dominance of yellow light in the morning - this is what causes us to wake up.
