Creator of ColorADD, the color alphabet for colorblind, a universal and inclusive language, which allows the inclusion of about 350 million colorblind people around the world.
ColorADD code was developed based on the three primary colors, represented by graphic symbols that, combined according to the basic concept of adding colors, allow the colorblind people to identify all colors whenever color is a factor of identification, orientation or choice.
Through co-creation models, this language is already implemented in several countries in different sectors of society, promoting the inclusion of colorblind people.
Also created a non-profit organization, ColorADD.Social, who promotes a set of actions carried out in Primary Schools to extend this code to education, allowing the inclusion of colorblind children without discriminating.
