The Saturation tool tones an image by changing the saturation and contrast of neighboring pixels.


The basic tool settings are shown in the Tool Options panel above the Image Window or by right-clicking on the image. To display the full list of parameters, press the tool icon in the Tool Options panel or use the F5 key. To specify the parameter settings, enter a numerical value in the parameter’s field or use the slider.

In addition to the above-mentioned parameters, you can adjust the advanced settings that affect the shape and position of the brush marks.


Press the Default button to set all settings to their default values.

To change saturation in a straight line, pick a starting point by left-clicking the mouse, then, while pressing Shift, move the cursor to the desired end point and release Shift. If Shift is not released, then a new line will be drawn to each point where the mouse is clicked.
