An app to help the colorblind with identification of colors.The app displays a portion of the devices 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 apps information screen.The app includes a flashlight button to turn the devices light on and off. It also includes a lock button to lock the cameras auto-exposure feature on devices that support this function. Exposure locking is often helpful in allowing the amount of light necessary for accurately capturing some colors, especially lighter and brighter colors.
