Ubisoft has unveiled Chroma, a real-time, open source tool designed to help developers make games more accessible for players with color blindness. The tool was announced at this week’s Game Accessibility Conference, following years of internal development by Ubisoft’s Quality Control team in India.

Built for developers, with inclusion in mindChroma simulates the three most common forms of color blindness—Protanopia, Deuteranopia, and Tritanopia—allowing developers to test in-game visuals through each filter without any performance impact. The tool is engine-agnostic, meaning it can be integrated into virtually any game, regardless of the tech stack.

With around 300 million people worldwide affected by color blindness, Chroma aims to make accessibility a seamless part of both the creative and QA processes.

“Chroma was created with a clear purpose—making color blindness accessibility a natural part of the development pipeline,” said Jawad Shakil, Product Manager at Ubisoft. He noted that the team had to overcome key technical hurdles, including real-time performance issues and perfecting the underlying algorithm.

By collaborating with accessibility experts and iterating based on feedback, Ubisoft built a tool that streamlines testing while eliminating lag and visual inaccuracies.

A community-driven futureUbisoft has open-sourced Chroma to encourage adoption and collaboration across the games industry. “We invite everyone to benefit from it, provide feedback, and contribute to its future development,” said David Tisserand, Ubisoft’s Director of Accessibility.

Developers can explore and contribute to Chroma on GitHub.
