ground color, the secondary suppression Hue and the direction (Angle)
will be different from primary suppression. Primary suppression removes
the backing color, while secondary suppression corrects the color in trans-
lucent areas.
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.
