Although the use of a specific color-blind glasses can make the person see all the colors, there is a color system called ADD, idealized by Miguel Neivas, 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 must learn that red corresponds to a drawing, while yellow has another drawing and so does blue.
This technique can also be used for people with achromatopsia, for example. See the symptoms of this disease similar to color blindness.

Color blindness is a genetic disorder that especially affects men and has no cure or treatment whatsoever and the only way for people with color blindness to know how to identify color is through this method.
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 still not possible to close the diagnosis because in the child's imagination the sky may be pink and therefore the tests may be false. Therefore, the diagnosis is usually made later, when the child collaborates better with the tests.
