    obtaining a first color from one of the plurality of pixels,extracting color components from the first color and a second color,determining, for each of the color components, a distance between the first color and the second color, andcombining the distances for the color components to obtain the normalized value for each pixel, wherein the normalized value equals the combined distances multiplied by a number;

    instructions for obtaining a sum, of the normalized values for the plurality of pixels, that is compared to a threshold, wherein a first image includes the plurality of pixels, wherein a result of the comparison indicates whether the first image matches a second image that includes the second color;

    instructions for determining whether one of the pixels that includes the first color is to be copied to a whiteboard, and displaying the whiteboard via a graphical user interface; and
