Sim Daltonism is a free macOS utility that simulates how colors appear to people with various types of color blindness. Users can move the Sim Daltonism window over any content on their screen to preview how it looks with different forms of color vision deficiency, including red-green, blue-yellow, and monochromacy. Designers, developers, and accessibility professionals use it to check whether websites, user interfaces, and visual designs are distinguishable by color-blind users. The app helps developers build more inclusive interfaces and allows anyone to better understand color blindness.
AI Recommendation
1 suggestionA native Apple Silicon build of Sim Daltonism has been confirmed running on real Macs in the Rosetta Check community. Anyone still running an older Intel-only build under Rosetta should update directly from the official source to get the native version, which will perform noticeably better on M-series Macs. The latest build is available through the Mac App Store or directly from Michel Fortin's website.
