An app to help the colorblind with identification of colors.The app displays a portion of the device’s camera, along with a small square sight. Upon snapping a picture (which is not stored on the device), the app first averages the red, green, and blue values of the pixels contained within the sight. It then suggests names for the color using three different methods, methods which are described in detail on the app’s information screen.The app includes a “flashlight” button to turn the device’s light on and off.
