A life «in colour» - what does it mean for a person? What role plays color in our daily life? As it turns out, considerable. And, moreover, it is not easy to realize in the life of people who do not distinguish between, because Daltonism in everyday life creates certain difficulties in such people.

Psychologists argue that certain colors may even cause drowsiness or hunger. So choosing yourself outfit remember that the color is very important.
How can you see the world in other people's eyes? It's hard to say which colors are different people, since the color perception is very subjective. As possible with confidence to declare that all people are equally perceived red? Perhaps for someone, a red box seems bright red, and for the other - light red. You can easily argue with someone about the fact that the pants of a dark blue or black color, but it is not possible to determine exactly who is closest to the truth, because it is not possible to look at the world through the eyes of another person.
If you look at the rainbow, the usual person will see seven main flowers leatherSPSF - «Every hunter wants to know where the pheasant sits». Where: K - red; O - Orange, Well - Yellow, Z - Green, G - Blue, C - Blue, F - Violet. But what will see a dongeon or a person with a violation of color vision? Nothing special and fun.
The colors of the rainbow help scientists understand that they see people suffering from deteanopia and protoropy (lack of perception of red and green flowers), as well as Tritanopia, and how it affects their world vision.
Dateranopia is a weakness of red perception when a red dress seems green-gray, the perception of purple color and skin color changes.
Protandopia is very similar to the deteransopy, only in this case the red dress seems the darker gray.
Tritanopia - when yellow is perceived as pale pink. A person does not perceive orange at all, there is a distortion of blue and red shades. Man sees all objects in the shades of pink and blue colors.
Trichromats with difficulty can determine pure green, yellow and red colors. They may not even notice the difference between purple and blue objects, since purple color partially consists of red.
Monochromates perceive everything in the form of black, white and gray colors. So all the colors of the rainbow seem to be blurry slightly. On the other hand, some types of violation of color perception should be considered not an anomaly, but rather - a feature of sight. According to research by British scientists, people who are difficult to distinguish between red and green colors can distinguish many other shades. In particular, the shades of the khaki color, which seem to be the same people with normal vision. Perhaps, in the past, such a feature gave its carriers evolutionary advantages, for example, helped find food in dry grass and leaves.
One of the most popular tests was considered Ishihara plates (Ishihara Plates) or still called pseudo-chromatic signs. Such a testing system was designed specifically for checking the soldiers of the Japanese army to distinguish colors by Dr. Science Shinoba Ishihara (Shinobu Ishihara). The plates were circles with crooked watercolor paints with colored dots, in the middle of which the colors were withdrawn by the paints. But this test had its drawbacks - sometimes the colors of the background and the numbers were so different that it was impossible to notice them, or, on the contrary, the wrong light dimmed the color of the numbers, thereby complicating the task even for people with normal vision.
When taking a fleet, each recruit must pass the color perception test. To check them use the so-called FALANT test, when the participants offer to the distance determine which light the lighthouse radiates. Simultaneously lights two lights from possible three - red, green and white. However, the light is passed through special «Filters», Due to what color «muffled». This is done so that the ranges cannot determine the light by its brightness. Such testing does not pass dichromates and most of the trichromates.
It is believed that the most accurate results of the inspection of various types of color is given an anomaloscope. On one side of the screen, the subjects offer a certain color, for example, yellow, and on the other hand, a mixture of colors, such as red and green. The studied must mix two colors offered on the other side to obtain identical colors on both sides. People with normal vision do not have difficulty mixing colors, while the bloomanomals cannot achieve a positive result.
This catastrophe led to the fact that when admitting to work in the transport service, it was mandatory to evaluate the color. And now, if a person has revealed Daltonism, the rights to driving a vehicle to him, alas, «do not shine».
The colors of the rainbow please us aesthetically and serve us with visual signposts, but whether we need it all? It is worth thinking about it.
When the architect plans the building design, it takes into account all the little things so that guests are satisfied, in order for even people with physical disabilities feel conveniently. But does anyone take into account the color vision disorder? Probably because such disorders are invisible in the appearance of man, many people do not even think about it and do not try to do anything. After all, how can I explain to a person what a green color looks like, if he never saw him? Of course, this color can be tried to describe, but still a Daltonian will not be able to present it as ordinary people see him.
In the daily life of the ranconies often feel disappointment. They try to buy non-rigid monophonic clothes to accidentally do not come to a party in a multicolored and incurred outfit. Children feel awkward during the drawing lesson, if pencils or paints do not have indicative designations. And the most, probably, hard to listen to when other people talk about beautiful, bright things, and you can't see them.
And although the ranktonists cannot become pilots, electricians or makeup artists, there are a number of other professions in which they can show themselves. For example, graphic design. Do not make hasty conclusions. This work can really come in color. First, the design of sites is not always based only on different colors to allocate important information. Sites designers also use other ways to attract attention, for example, different font or contrast. Secondly, all colors on the Internet are arranged in a hexadecimal system. Blue color, like everyone else, has its own code - # 0000FF. Therefore, people who do not distinguish with colors can remember the codes of shades and calmly color the pages of sites.
