What Color?

This app is a lifesaver for those of us who are colorblind. I was going to work on writing such an app myself, but took a quick look on the Android Market and found this once. It works well. Although my Atrix camera colors are a bit off (no fault of What Color?), What Color gets me over the red/green hump. The only way I can think of to improve the app is to develop color calibration profiles for the more popular devices. One way I thought of doing this was taking photos of a reference test image.

this is very helpful for my red-green colour blindness. When I navigate away from the app, it locks up, and can be very hard to close without rebooting the phone. I have a Nexus 5 running 4.4.4. It would be great if the dev can fix this. Thanks.

This is somewhat helpful but I can't really truat it since even as a color challenged individual I can tell that it is inaccurate and leans strongly towards red shift on my device in my home This would be fine if there was a white balance tool.
