To access the Global Color Correction dialog box, click
the color balance button .
A range of colors can be represented in a color wheel.
The color wheel in this dialog box is composed of the
three primary colors, red, green, and blue (RGB), and
their complementary colors, cyan, magenta, and
yellow (CMY).
To adjust a color, increase or decrease the amount of
its complementary color. For example, if you have an
image with too much green, you can reduce the green
by increasing its complementary color, magenta.
(Magenta is opposite green on the color wheel and
color sliders.)

Across the top of this dialog box is a series of buttons
25% 50% 75%
that enable you to specify the midtone range you want
to edit on your image.
You can select all ranges, or you can choose one or
