The Saturation color adjustment layer changes the saturation intensity of your photograph's colors. PhotoPad's Saturation layer can be used to make your photograph's colors more vibrant, or even to add an artistic dullness. Add a saturation layer by clicking the Saturation icon on the Color tab of the toolbar.
Use the Saturation: slider to make your image more dull or vibrant in color
Use the Prevent Oversaturation checkbox to enable oversaturation prevention of images. When enabled, this will prevent saturation artifacts.
