Using the Hue/Saturation command
The Hue/Saturation command lets you adjust the hue, saturation, and lightness of the
entire image or of individual color components in an image. Adjusting the hue, or color,
represents a move around the color wheel. Adjusting the saturation, or purity of the color,
represents a move across its radius.

Color wheel and radius of color wheel:
A. Saturation B. Hue C. Brightness D. Hues
You can also use the Colorize option to add color to a grayscale image converted to RGB,
or to an RGB image—for example, to make it look like a duotone by reducing its color
values to one hue.
To use the Hue/Saturation command:
1 Open the Hue/Saturation dialog box. (See
The two color bars in the dialog box represent the colors in their order on the color wheel.
The upper color bar shows the color before the adjustment; the lower bar shows how the
adjustment affects all of the hues at full saturation.
2 (Photoshop) For Edit, choose which colors to adjust:
Choose Master to adjust all colors at once.
•
Choose one of the other preset color ranges listed for the color you want to adjust.
•
An adjustment slider appears between the color bars, which you can use to edit any
range of hues. (For information on how to modify the slider's range, see the instructions
following this procedure.)
3 For Hue, enter a value or drag the slider until the colors appear as you want.
The values displayed in the text box reflect the number of degrees of rotation around
the wheel from the pixel's original color. A positive value indicates clockwise rotation,
a negative value counterclockwise rotation. Values can range from –180 to +180.
4 For Saturation, enter a value or drag the slider to the right to increase the saturation or
to the left to decrease it.
The color shifts away from or toward the center of the wheel, relative to the beginning
color values of the selected pixels. Values can range from –100 to +100.
5 For Lightness, enter a value or drag the slider to the right to increase the lightness or to
the left to decrease it. Values can range from –100 to +100.
