A mobile electronic device includes a transparent display screen for comparing and accurately determining the color of a predetermined object, for various applications, including augmented reality. Color data for a perceived color stores in a memory and displays images as perceived through the transparent display screen. Image difference values are determined between a first set of optical processing data and a second set of optical processing data. The transparent display screen indicates image difference values from including differences in color, texture, transparency, lighting, etc., especially for augmented reality applications. A memory stores optical processing data and optical processing instructions and algorithms. A computer processor executes optical processing instructions and algorithms and in response to optical processing data generated. An optical lens captures an image of an object for display on the transparent display screen. A transparent portion of the transparent display screen of the mobile electronic device displays the object.
