3 Adjust the Hue slider.
The Hue value represents the change from the original pixel color
as the number of degrees of rotation around the 360-degree color
wheel. A positive value indicates a clockwise rotation, and a
negative value indicates a counterclockwise rotation. For example,
when the Hue value is 180, blue becomes yellow, and green
becomes magenta.
4 Adjust the Saturation slider.
Dragging the slider up increases the saturation; dragging it down
decreases the saturation. Values range from –100 to 100. A value
of 0 preserves the original setting.
5 Adjust the Lightness slider.
Dragging the slider up increases the lightness; dragging it down
decreases the lightness. Values range from –100 to 100. A value
of 0 preserves the original setting.
6 Click OK.
You can turn an image into a duotone (two-color) image by
marking the Colorize check box, which converts the image to
grayscale. To colorize the image, you can select a hue and
adjust the saturation and lightness values.
