The Hue-Saturation tool is used to adjust hue, saturation, and lightness levels on a range of color weights for the selected area or active layer.
The Hue-Saturation dialog window allows the selection of the color range that will be affected by the sliders. The colors are listed on the left side of the dialog and can be selected individually for tighter control or globally using Master for changes that will affect all pixels.
