Hue/Saturation lets you adjust the hue, saturation, and lightness of a specific range of colors in an image or simultaneously adjust all the colors in an image. This adjustment is especially good for fine-tuning colors in a CMYK image so that they are in the gamut of an output device.
Apply a Hue/Saturation adjustment in Photoshop
- Do one of the following:
a. Click the Hue/Saturation icon in the Adjustments panel.
b. (CS5) Click a Hue/Saturation preset in the Adjustments panel
c. Choose Layer > New Adjustment Layer > Hue/Saturation. Click OK in the New Layer dialog box.
- 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.
a. Choose Master to adjust all colors at once.
b. Choose one of the other preset color ranges listed for the color you want to adjust. To modify the color range, see Specify the range of colors adjusted using Hue/Saturation
c. (CS6) Choose a Hue/Saturation preset from the Preset menu.
- For Hue, enter a value or drag the slider until you are satisfied with the colors.
The values displayed in the box reflect the number of degrees of rotation around the wheel from the original color of the pixel. A positive value indicates clockwise rotation; a negative value, counterclockwise rotation. Values can range from ‑180 to +180.
