Although the use of specific glasses for colorblind people can see all colors, there is a color system called ADD, designed by Miguel Neiva, which can be used in all types of color blindness.
The system consists of assigning a symbol for each primary color: red, yellow and blue and then the color combination can also be 'seen' by the colorblind, because the symbols can be integrated. Thus, for the colorblind to learn to differentiate colors, he needs to learn that red corresponds to a drawing, while yellow has another drawing and in the same way with blue.
This technique can also be used for people with achromatopsia, for example. See the symptoms of this disease similar to color blindness.
Steps for the colorblind learn colors
The first step for the colorblind to be able to identify the colors is to learn the symbols that correspond to each of the primary colors, which are yellow, red and blue. After learning the symbols corresponding to the primary colors, the colorblind must learn to differentiate the black color from the white color, in order to be able to identify the light shades and the dark shades, as represented in the image:
After knowing which symbols correspond to each of the primary colors and the color obtained from the combination of each of them, the colorblind must be able to differentiate the following colors, by combining the various symbols corresponding to the colors that give rise to them:
When the colorblind already knows how to identify the symbols corresponding to each of the colors and the symbols that correspond to white and black, he must also be able to distinguish the colors of light tones from the colors of dark tones:
This color system can be used to bring social inclusion and increase the self-esteem and independence of color blind people, when it is included in games, colored pencils, clothing labels, parking lots and traffic signs.
Color blindness is a genetic alteration that affects men especially and has no cure, nor any type of treatment and the only way for people with color blindness to know how to identify colors is through this method. Understand what it is and what are the types of color blindness.
Usually the suspicion of color blindness arises in childhood, when the child is learning colors, between 2 and 3 years of age. However, at this stage it is not yet possible to close the diagnosis, because in the child's imagination the sky may be pink and therefore the tests may be false.
For this reason, the diagnosis is usually made later, when the child collaborates better with the tests. Learn how to get tested for color blindness
