2 Use the eyedropper tool to click an area in the

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.

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 Do one of the following:
• Choose Enhance > Color > Hue/Saturation.
Create a new Hue/Saturation adjustment layer,
•
or open an existing Hue/Saturation adjustment
layer. (See "Using adjustment layers and fill layers"
on page 181.)
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.
For Edit, choose which colors to adjust:
2
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.)
For Hue, enter a value or drag the slider until
3
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.
