    ScanGear (scanner driver)'s  Basic Mode tab.
    Color Adjustment
    Correct colors that have faded with time or due to colorcast. "Colorcast" is a phenomenon where a
    specific color affects the entire picture due to the weather or ambient strong colors.
    Click an arrow in  Color Adjustment  to emphasize the corresponding color.
    Cyan & red, magenta & green, and yellow & blue are complementary color pairs (each pair produces a
    shade of gray when mixed). You can reproduce the natural colors of the scene by reducing the cast color and increasing the complementary color.
    It is recommended that you find a portion in the image where it should be white, and adjust the colors sothat the portion turns white.
