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 508.
