Are you curious to see how color blind people see the world? Download this app. Or if you're color blind, help is available. Just download this app.

Do not mistake this app for other color blind apps. Color De Blind not only shows you what it is like to be color blind, but it also modifies live video to help color blind people see the real world in ways they haven't before.

Color De Blind harnesses the graphics processor within your cell phone to run advanced color manipulation algorithms. These algorithms have existed on computers for some time, but have had limited utility to color blind people in the real world. Now, Color De Blind allows you to go anywhere your iPhone can go while experiencing colors in live, full-motion video.

Running these algorithms is no easy task, but finally the iPhone is able to make sense of a colorful, yet confusing environment. For every pixel your camera can see, the algorithms have to do 30 to 40 advanced algebraic problems. Just imagine taking 40 math tests for each one of the millions of pixels from your camera. Then imagine that Color De Blind is doing all those tests 30 times per second to show you a live video.

"This app will change the lives of color blind people in ways that no medical advancement has ever been able to. It's convenient, practical, and more importantly, useful to people who had previously been unable to distinguish between various colors. Aside from it's medical implications, it's also really helpful in showing people who are not color blind how debilitating and frustrating the condition can be." -Samantha Harris, M.D.

"Holy crap. That is amazing. I can see things I could never see before." - Tony D. (red-green color blind)

What would I do without it?


I love being able to use this app to see what my graphs will look like to my team members who can't always distinguish between colors.

Until I saw this app I never knew I was colorblind. I thought everyone saw what I did..... apparently not.

A must have for colorblind people

The other night, I was thinking, wouldn't it be cool to have an app that could let my friends, loved ones, and perhaps decorators see the colors I see. With a little searching, I found this gem. Not only does it do the job, it also provides me with what I'm calling my color flashlight where it highlights things I perceive as being the same color but that others see as being vastly different.

I'm finding that using it with others also lets me better understand my color blindness. For example, the other day I used it to show my girlfriend the difference I see between a purple shirt and a similarly toned blue napkin. (I used the color flashlight to double check which was which.) She said they now look the same while I could still queue in on the differences that I normally look for between the two.

The app has an iPad and iPhone version. The $.99 bought me both.
