							Adjusting Colors Using a Color PatternYou can preview color changes and reproduce natural colors by using the color pattern function in

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.
Preview image appears in the center. Preview image colors change as you adjust them.
