#game dev accessibility

Ubisoft has taken a significant step toward more inclusive game development with the global release of Chroma, an open source accessibility tool designed to help developers accommodate colorblind players. First revealed at the Game Accessibility Conference this week, Chroma has been in development since 2021 by Ubisoft’s Quality Control team in India. The tool simulates the three most common forms of color blindness—Protanopia, Deuteranopia, and Tritanopia—allowing developers to experience and adjust their in-game visuals through the lens of players affected by these conditions. This means developers can use it during the creative and testing phases without sacrificing gameplay speed or quality. Chroma can be easily integrated into development pipelines and used during game design reviews, art direction meetings, and user experience testing. It provides a visual overlay or simulation layer that allows dev teams to assess whether key gameplay elements—like HUDs, enemy indicators, health bars, and puzzle elements—remain visible and distinct under various colorblind conditions. As game accessibility continues to evolve, Ubisoft’s release of Chroma reflects a larger industry trend: building not just games, but experiences that can be enjoyed by everyone from the very beginning of development. “Building something like that from scratch has to be decided upon early in development so you have the time/resources allocated to make it properly,” said accessibility consultant Steve Saylor on Bluesky.
