10. Adjust the range of hues and saturation levels that are included as part of the background
as follows:
• Sat. range — Use the Hue knob to adjust the range of saturation values used for
background colors that are close to the primary color. The higher the value, the
larger the range of saturation levels.
~
Increasing the saturation range value causes a wider range of color saturation to
be included in the background, and therefore, keyed out.
~ Decreasing the saturation range value causes less of a color saturation range to
be included in the background. For example, only color saturations close to the
nominal value are included in the background.
• Positive hue — Use the SAT knob to expand the hues included in the background
counter-clockwise around the color wheel.
• Negative hue — Use the LUM knob to expand the hues included in the
background counter-clockwise around the color wheel.

Tip
The Background area will typically need only very minor adjustment
as most of the modification has been made by adjusting the Shadow
and Translucent areas. However, changing this range may help expand
or decrease these areas as they are completely contained in the
Background range.
