Sim Daltonism

Sim Daltonism lets developers check a game for colourblind readability in real time. Run the game through a colourblind filter and check whether critical information is lost. Sim Daltonism is a real-time tool that shows what the three major colour vision deficiencies see.

Color Oracle is named as a static alternative. Unreal Engine includes filters by default and Unity has plugins. Playtesting with colourblind gamers is described as better still.
