Balance adjustment as follows:
 Look at the image. Did the automatic color correction correct the
color cast in the image’s neutral color areas of black, white, and
neutral gray?
 Look at the RGB Parade monitor. Find the black and white areas
of the image, and then locate these areas in each of the red, green,
and blue channels. They should measure equal levels of red, green,
and blue.
5. If necessary, tweak the chroma values using the ChromaWheels to
further neutralize color casts in the image.
After a Color Balance adjustment, the blue
values in the highlights are a little too high
in this example, and the red values are a
little too low
Therefore, you would need to tweak the
chroma values in the ChromaWheel by
dragging the crosshairs away from blue
and toward red
