When we visualize data to communicate to others, we must consider what others see through their eyes. Sim Daltonism by Michel Fortin is a free app for the Mac that lets you see how those with various types of color blindness perceive what’s on your computer screen.

It’s simple to use. Just drag a window over any part of your screen to see the differences.
