low saturation value, while vivid colors have a high saturation value.

Low Gain
Use this to set the range of saturation values you want
$
to be partially affected based on the value set by the Low Clip control.
As you increase the Low Gain setting, more pixels are partially
affected by the color correction. If you decrease the Low Gain control,
less pixels are partially affected.
A Low Gain setting of 100 provides the widest range for maximum
color correction. Alternately, a gain setting of 0 creates a key where
saturation values are either completely affected or left untouched. You
can think of the Low Gain control as defining an "Affected to
Untouched" range for keying the pale colors in your image.
High Gain
This control is similar to the Low Gain setting, except
$
you use it to set the range of higher saturation values you want to be
partially affected based on the value set by the High Clip control. As
you increase the High Gain setting, less pixels are partially affected
by the color correction. If you decrease the High Gain setting, more
pixels are partially affected. You can think of the High Gain control
as defining an "Untouched to Affected" range for keying the vivid
colors of your image.
High Clip
This control is similar to Low Gain , except you use it to
$
select the higher saturation values to be keyed.
¦ Note
The values you can select using the Low Clip and Low Gain
controls are dependent on the High Clip and High Gain controls, and
vice versa. This prevents the low and high controls from keying on
the same values.
Luma Key
This type of key lets you select areas to be keyed (affected

by the color correction) based on their luminance value.
