Controls the fade effect of the underlay. Values range from 0 through 100. The greater the value, the more transparent the underlay appears against the background. The lesser the value, the less transparent and closer to opaque the underlay appears. A value of 0 makes the underlay appear fully opaque.
Controls the color saturation of all linework while maintaining the luminance. When turned on, the linework appears in varying shades of gray starting at black if the background color luminance is 50 percent or more. If the background color luminance is less than 50 percent, then the colors are inverted, with the darkest linework displaying in white, and the lightest linework displaying in black.
