About Sim Daltonism
Sim Daltonism shows colors as they are perceived with various types of color blindness. On the Mac it filters a region of the screen, so you can check a design, chart or photo as you work; on iOS it filters the live camera view.
It is useful for designers and developers who want to see whether colors in their work can be told apart. The project is open source and published on GitHub.
