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)

Incredible parenting tool!

I have a 6-year-old with protanopia and after a frustrating experience with a board game that we had to take a Sharpie to to make it useable to him, I stumbled across a forum that sent me to your app.

This. Is. Amazing! After years of trying to guess which colors were challenging to him in each context, I can literally see for myself! I spent about 20 minutes just walking around my house with my mouth agape, seeing our home -and us! -the way he does. It is rare that we can truly experience what a challenge is like for someone else -and this app did just that. (I see what he means: unripe and ripe bananas are identical!)

This is going to be an incredibly helpful tool for us and I'm going to tell his teachers about this app too. Thank you for quite literally giving us a view into his world.

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.

A bit clunky.

I like it, though it could have simulation of partial color deficiency, maybe with a slider for how much. It might also use some “About…” text popup that explains the app and how to use it.

The single-view display does not clearly show what processing is applied to that view, or how to change it. No processing is only displayed when doing color-value capture with a square at the center of the view.

The multiview could also include no processing. It could display only deficiency selection, only color enhancement, or making some color white, making 4 at a time.

One might also mention simulating dog vision - dogs have red-green color deficiency.
