Hue/Saturation
You can modify the tint and purity of specific colors with the Hue/
Saturation command. In terms of image editing, saturation refers to
the amount of gray in colors.
The Hue/Saturation dialog box varies slightly depending on the color
mode. For RGB Color and CMYK Color images, you can modify
red, yellow, green, cyan, blue, or magenta color ranges. For LAB
mode images, you can modify blue, magenta, yellow, or green color
ranges.
The Hue/Saturation command is available when you work with
CMYK, RGB, or LAB Color mode images. Before choosing the
Hue/Saturation command, make the composite channel active. For
more information, see Activating channels on page 33.674.
