In this paper we will discuss the work we are doing within the Game4CED project regarding board games and dyschromatopsia. The term dyschromatopsia indicates a condition of hypo-functioning of a class of cones which leads the subject to confuse colors or perceive some of them in a limited way. Approximately 9% of men and 1% of women are affected by some kind of color deficiency. With this research project we analyzed if modern board games are fully playable by people with color vision deficiency and we tried to utilize a board game designed by us to identify children with this type of vision deficiency. To do so we have analyzed the visual accessibility standards of many modern boardgames, created a method to evaluate these standards and, above all, created a board game called ColorFit. ColorFit is a free abstract board game for two players that requires players to associate colored tiles with colored areas presented on the game board. This simple task associated with specially designed color palettes allows us to estimate if players are viewing colors correctly or have perceived some type of chromatic alteration due to dyschromatopsia.
