Exploring the Impact of Colour-Blindness on Computer Game Performance.

We assess the effects of colour-blindness on casual computer gaming performance and experience. Participants played an online puzzle game in both an unmodified environment and in a colour-blind simulation. Some of our results suggest that the colour-blind filter did not negatively impact player performance. However, users perceived the game as more difficult and their performance as limited. These contradicting results highlight the importance of further understanding the impact of colour vision deficiency on performance, and the accessibility principles used in game design when colour coding operable cues.
