Note If Reshape has been applied, it is unlikely enough edge detail will remain to
use secondary color suppression.

2. Adjust secondary suppression Hue and Selectivity so that the translucent
area is affected, but opaque areas of the foreground are not. The final
hue will lie somewhere between the backing color (primary
suppression hue) and the uncorrupted foreground color.
• When making this adjustment, it is helpful to turn the secondary
Chroma Suppression to maximum, and the secondary Suppression Angle
to produce an unnatural color in the affected area. This makes the
changes to secondary suppression more obvious.
• Selectivity should be kept as wide as possible. You should only
narrow selectivity (increase its value) if you cannot avoid changing
opaque areas of the foreground.
3. Adjust the secondary Angle so that changing secondary Chroma
suppression moves the color in the desired direction. You are trying to
match the color of the translucent areas to an opaque (uncorrupted)
area of the foreground subject.
