Tutorial: Hue and Saturation

Hue refers to a color without tint (added white) or shade (added black). Hue permits colors to be classified as red, yellow, green, blue, or an intermediate between any contiguous pair of these colors.

Saturation is the degree of a chroma or purity of a color – that is – the degree of freedom from being mixed with white. Saturation defines a range in color from pure color (100%) to gray (0%) at a constant lightness level. Pure colors are fully saturated.

  • 1. Open up the image
  • 2. To find the hue/saturation window in Photoshop you can do one of three things:
    • Go to Image -> Adjustments -> Hue/Saturation
    • Use the keyboard shortcut of CTRL + U (Windows) or CMD + U (Mac)
    • Use the hue/saturation icon in the side panel
  • 3. Using the MasterĀ option you can use the sliders to change how the entire image looks
  • 4. Using the various color options you can change any specific parts of the image by using the sliders. (If the particular color you wish to choose is not listed in the drop-down list you can choose any color and then click on a color in the image using the eyedropper.)
  • 5. Change the “Color” option in the drop down list to green and use the sliders to determine what green is left to change.
  • 6. Using the eyedropper tool (in this case, the additive eyedropper) you can change the amount of colors that are sampled.
  • 7. After all the leaves are chosen you can use the sliders to change the hue and saturation of the leaves.
