Saturation Scale This value is used as a multiplier to increase or decrease the saturation of the colors in the theme using the HLS (Hue Lightness Saturation) framework. • A higher multiplier (greater than 1 ) increasingly makes the colors a more vibrant hue. • A lower multiplier (between 0 and 1 ) dims the colors toward a gray -scale. To Change the Saturation Scale: Type a value into the text box, or left-click and drag the slider to the left or right.
