Modifying Color Values

The color wheel in the 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.
There are two ways to adjust the color values:
Color wheel
Color sliders
The numeric values above the color wheel shift as you make changes.
Only active color ranges are affected by your changes.
Click and drag to move the white point to a different
color orientation on the wheel. The image's color
balance shifts accordingly.
Drag the color sliders back and forth between the
complementary colors.
