Free For All – Color Blindness Simulator

Have you considered how your digital maps look to those with color blindness? Are you trying to improve your color ramps to find ones that everyone can see, even those who have tritanopia? If so, here is a lightweight freeware application that does just that, Color Oracle.

Once installed, you can easily toggle your screen colors to simulate three color blind conditions: deuteranopia, protanopia and tritanopia. Once you toggle between the various view modes, your screen is transformed to a new color palette so you can evaluate if the colors you choose are visible to everyone. And once you click your mouse or keyboard again, the color palette is instantly returned to normal. This application works with both Windows, Mac and Linux operating systems which is an added bonus!

Until my next edition of Free For All, happy hunting for free geospatial goodies!
