This is the question posed by Dan Kaminsky, a security researcher known for . Kaminsky has released a side project called , an experimental app inspired by a friend who is colorblind. DanKam uses the camera on an iPhone or iPod touch to tweak the color of whatever item you point the device at, ideally making real world objects more discernible to color-blind individuals. Additionally, you can access any photo you've saved in your device's camera roll or albums and tweak it.

DanKam is targeted at who, according to Kaminsky's research, experience the most common form of color blindness, in which reds and greens shift towards each other in the color spectrum (for bonus geek points, he even uses a scene from J.J. Abram's with an infamous green woman to demonstrate the effect).

The app offers a number of customizable settings, but Kaminsky admits this is experimental technology in need of a bit of polish. You can pick between different modes and filters that can convert colors to specific parts of the spectrum, swap colors, increase saturation, adjust white balance, and more. The app also contains a series of .

Kaminsky is openly soliciting feedback--especially from DanKam's target audience--on the utility and future direction of the app. If you're colorblind or know someone who is, $3 doesn't sound like too steep of a price to help shape a budding new type of iOS app.

DanKam is available now in the App Store, and it requires an iPhone or iPod touch running iOS 4.0 or later.
