Color Alerts allows users to be alerted by all their favorite colors. NO additional equipment needed!! You will only need this app to begin being alerted by your favorite color(s). The Color Alerts capture button, located at the bottom center of the screen will save the color being viewed on the screen, then allow users to select an appropriate alert they wish to hear when the camera sees the favorite color, or colors. You are able to save and view all the favorite colors by selecting the color icon in the top left corner of the screen. Here is also where the appropriate box(s) for the color(s) you wished to be alerted for can be checked or unchecked. The colors not currently in use can be muted by unchecking the appropriate box. When selecting the favorite color from the home screen you can more accurately be alerted to your color by adjusting the zoom feature, found above the capture button, and also adjusting the diameter of the area which to be captured, found along the middle right side of the screen. To be alerted for the color is simple! Once the focusing is completed and your phone is on a stable platform, you will be alerted the next time the color presents itself within the capture window shown on the screen.
