Hue/Saturation effect
The Hue/Saturation effect adjusts the hue, saturation, and lightness of individual color components in an image. This effect is based on the color wheel. 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. Use the Colorize control to add color to a grayscale image converted to RGB, or to add color to an RGB image.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
- Channel Control
- The color channel you want to adjust. Choose Master to adjust all colors at once.
- Channel Range
- The definition of the color channel chosen from the Channel Control menu. Two color bars 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. Use the adjustment slider to edit any range of hues.
- Master Hue
- Specifies the overall hue of the channel chosen from the Channel Control menu. Use the dial, which represents the color wheel, to change the overall hue. The underlined value displayed above the dial reflects the number of degrees of rotation around the wheel from the pixel’s original color. A positive value indicates clockwise rotation; a negative value indicates counterclockwise rotation. Values range from –180 to +180.
- Master Saturation, Master Lightness
- Specify the overall saturation and lightness of the channel chosen from the Channel Control menu. Values range from –100 to +100.
- Colorize
- Adds color to a grayscale image converted to RGB, or adds color to an RGB image—for example, to make it look like a duotone image by reducing its color values to one hue.
- Colorize Hue, Colorize Saturation, Colorize Lightness
- Specify the hue, saturation, and lightness of the color range chosen from the Channel Control menu. After Effects displays only the sliders for the Channel Control menu choice.
Adjust colors with the Hue/Saturation effect
- Choose Effect > Color Correction > Hue/Saturation.
- From the Channel Control menu, choose which colors to
adjust:
-
Choose Master to adjust all colors at once.
-
Choose a preset color range for the color you want to adjust, and then use the sliders for that color range.
-
- For Hue, type a value or drag the dial.
- For Saturation, type a value or drag the slider. The color shifts away from or toward the center of the color wheel, relative to the beginning color values of the selected pixels.
- For Lightness, type a value or drag the slider.
Colorize an image or create a monotone result
- Choose Effect > Color Correction > Hue/Saturation.
- Select Colorize. The image is converted to the hue of the current foreground color. The lightness value of each pixel doesn’t change.
- Drag the Colorize Hue dial to select a new color if desired.
- Drag the Colorize Saturation and Colorize Lightness sliders.
Modify the range of Hue/Saturation effect adjustments
- From the Channel Control menu, choose an individual color. (By default, the range of color selected when you choose a color component is 30° wide, with 30° of fall-off on either side. Setting the fall-off too low can produce dithering in the image.)
- Do any of the following:
-
Drag one or both of the white triangles to adjust the amount of feather without affecting the range.
-
Drag one or both of the vertical white bars to adjust the range. Increasing the range decreases the fall-off, and vice versa.
