Ubisoft has introduced Chroma, an open-source color simulation tool designed to enhance accessibility for gamers with color vision disorders, estimated to affect around 300 million players globally. Unlike tools limited to specific games, Chroma is compatible with various game development platforms and tools, making it widely applicable across the industry.
The tool effectively simulates the three most prevalent types of color vision disorders: Protanopia, Deuteranopia, and Tritanopia. By applying visual filters to game visuals, developers can experience and evaluate gameplay from the perspective of players experiencing these disorders in real time. This approach aims to foster the creation of more inclusive and accessible game experiences.
A key feature of Chroma is its capability to render simulated imagery at up to 60 frames per second. Although this frame rate may not be considered high by contemporary industry standards, it is sufficient for testing scenarios where maintaining image accuracy is paramount. Additionally, Chroma offers functionalities such as live gameplay recording, screenshot capture, a user-friendly interface, and support for both single and dual monitor setups.
The development of Chroma, which began in 2021 by Ubisoft’s Quality Control team in India, utilizes the Color Oracle algorithm—an established tool known for simulating color vision disorders, commonly used by graphic designers and developers. The team has enhanced performance and accuracy by implementing additional keyboard shortcuts, overlay options, and technical refinements aimed at minimizing simulation latency.
Jawad Shakil, Product Manager for Ubisoft’s Quality Assurance team, highlighted that Chroma was conceived with accessibility as a central focus from the early stages of game development, rather than as an afterthought. By making Chroma open source, Ubisoft aims to empower the global game development community to enhance the gaming experience for players with color vision disorders, fostering a more efficient and sustainable approach to accessibility in gaming.
