A sizable segment of the population suffers from color blindness, enough so that it’s worth considering the implications on color palettes and usability. This tool allows you to simulate the ways that various color vision deficiencies will affect you imagery. I’ve noticed that some of the images we create probably won’t read very well to some people, and this easily lets us check if we’ve created something that could be ambiguous.

It’s not a perfect simulation, since it only does a linear color transform, not accounting for local color frequency, and it doesn’t account for any output specific color shifts. Nothing unusual when it comes to color, of course. Typical things to consider, colors may look different on an LCD screen compared to web offset printing.
You can use this as a viewer macro, though I may at some point make a proper Cg viewshader.
