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.

2
In the Effect Controls panel, click the Setup icon

•
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.
