Colourblindness, or colour vision deficiency, affects approximately 10% of men and 1 in 200 women – approximately 350 million people around the world. There are different forms of colour blindness, including the total inability to perceive colours.


ColorADD transforms colour to a graphic code that indicates the colours on textiles, medicines, educational games, coatings, paint material etc. Based on three primary colours, the symbols are related to each other and the entire colour pallet graphically identified (for example, yellow and blue make green; the symbols of the graphic code are similarly combined).


Currently, ColorAdd is used in many different areas such as education (school utilities, manuals and books, educational games, etc.), textiles and footwear, healthcare systems, transport systems, food industry, teaching materials, city administration, science, culture etc. The  ColorADD is also used in the Portuguese National School Exams to facilitate the correct interpretation of colour and consequently the contents of exams. Delivering innovative projects in more than 35 different areas, ColorADD is obtaining visibility and recognition on a global scale from business, institutional and academic communities, as well as wide media coverage: Le Monde, France Press, Vogue, Folha de São Paulo, Globo TV, among others.
