Color Blindness Simulator

Color Oracle is a free app that makes simulating color blindness easy, allowing for a real time look at how those with different types of color impairments will view images on screen. The utility “takes the guesswork out of designing for color blindness” and according to it’s developers, uses the best available algorithm for simulating color recognition impairments.

Color Oracle is available as a free download for Mac OS X, Windows, and Linux, and a valuable addition to any designers toolkit.

Considering that color blindness effects as high as 8% of the male population, if you’re a print, web, or app designer, you’ll want to know what your creations will look like to those who are affected.

Thanks for the tip Henrik

    I thought that Red-Green color blindness was the most common. It’s not one of the options on this app.

    My friend has that type of color blindness and it has caused some interesting situations at times.

    I always have trouble with charts that use color. i can tell there is a difference between the adjacent colors but matching those colors to the key is the problem. It is particularly bad for reds,green,brown pink,purple red,orange,yellow.

    It would be great if there was a fix..

    I’m not a designer but I’ve always wondered what color blind people see. Looks very strange to me, but must be normal for them.
