Color Adjustment button

Click this button, and the Color Adjustment dialog box will

appear:

Color Adjustment is another

convenient tool that you can use to

adjust and calibrate the colors in an

image. This function works much like

the Color Balance tool, but it

provides another way to control the

property of image colors.

The Color Adjustment tool uses three control items: Hue,

Saturation and Lightness. Hue is a characteristic that distinguishes

one color from another, while Saturation decides the intensity of a

color. Lightness is used to measure the amount of brightness in a

color. The lighter a color is, the higher brightness it has.

Color Wheel: Color Wheel is where you can specify

the hue and saturation of the color you want to use.

Move your mouse cursor on the Color Wheel and

then click on it. Drag within the Color Wheel to select

the hue of the color you want to use. The distance

from the center of the wheel decides the saturation of

the color: the farther you drag your mouse cursor

from the center of the Color Wheel, the higher the

saturation.

Lightness Bar

You can drag the triangle below the Lightness Bar to

adjust the lightness of the color you choose. To

increase the lightness, drag the triangle to the right.

Otherwise, drag the triangle to the left to reduce the

lightness.
