Isolate a single color using Color Pass
The
Color Pass effect lets you isolate a single color or a range of
colors. Adjustments are made in a dialog box showing the Clip Sample
and Output Sample. You can also adjust the Color Pass effect properties
in the Effect Controls panel.

If you want
to color correct a single color or range of colors in a clip, use
the Secondary Color Correction controls in the Color Correction
effects.
- Drag the Color Pass effect to a clip.
- In the Effect Controls panel, click the Setup icon
for
the Color Pass effect.
- In the Color Pass Settings dialog box, do one of the
following to select the color that you want to preserve:
Move the pointer into the Clip Sample (the
pointer turns into an eyedropper) and click to select a color.
Click the color swatch, select a color in the Adobe
Color Picker, and then click OK to close the Adobe Color
Picker.
The selected color appears in the Output Sample.
- For the Similarity option, drag the slider or enter a
value to increase or decrease the color range to be preserved.
- To reverse the effect, so that all colors except the
specified color are preserved, select the Reverse option.

To animate this effect, use the keyframe
features in the Effect Controls panel.
