Like most colorblind people, a colorblind Microsoft engineer wanted to be able to distinguish colors better and to get an idea of what the rest of the world saw. To help him do that, he worked with another Microsoft software engineer to create a new app. Called Color Binoculars, the app is iOS only at this point so I haven't really given it a shot yet. I'll have to dig out my cranky old iPad and see how it works on that so I can update this with my impressions.
The app has selections for the most common types of colorblindness and enhances color differences to help colorblind users differentiate colors. It's like a digital approach to what the EnChroma glasses are supposed to do.
For now I wanted to put this out there and get more attention on it in case others might find it useful. You can find out more about it on the Microsoft Blog.
