In the first year of the study Communication and Multimedia Design, I made a poster about color blindness. The game Two Dots was the center point of the poster. In their game, you can use a colorblind mode, that works so perfectly!
The poster was done. But I thought I could learn more about this subject, so I decided to make manual right away. It is focused on (Interaction) Designers, where they can look up what will and will not work for the various sorts of colorblindness.
