Have you thought ever about is which RGB code of your eye color? :) This day has come:
This tiny app can read colors by device camera and represent a result to the RGB format. You can store results and in the "storage menu" edit or delete colors. Tap and hold on color for multi select mode. Tap on RGB Hex code to copy it to clipboard. If you want you can add values of R, G or B channel manually. Adjust color by saturation bar or value bar.
Note: accuracy of results depend on camera features and can be different on various devices.
