Chromoculus

Are you having trouble distinguishing between red and green or yellow and blue?
Then Chromoculus might be the app for you: It displays the live camera image while processing the critical colors so you can distinguish them. For example, you can see previously unrecognizable items and even see or read red text on a green background.
In automatic mode, the colors that are indistinguishable to you flash in the camera image. Thus, you can see at a glance whether you have missed something important. In manual mode you can determine the intensity of the color adjustment yourself for enhanced readability. Currently, red-green and blue-yellow color blindness are supported.
