Abstract
Disclosed are methods and devices for color compensation of a display having a translucent display cover applied to an outside surface of the display. A method may include characterizing a color shift due to the translucent display cover for when there is rendering of an image on the display and compensating for the color shift when rendering an image on the display. The method further may include measuring the color shift induced by the color of the finish, and as described below compensating the red, green, and blue (RGB) levels of the display so that the display image may be presented to the user as originally intended. In this way, the image quality may be substantially optimized for viewing regardless of the lens/cover surface color.
