Suppressing Color Spill

Use the Color controls to reduce the saturation of the unwanted color.

To suppress a color in the image:

1. In the Keyer Controls panel, click Result in the Output options so that you can see the color spill on the image in the viewport.
2. By default, the color that is suppressed is the key color. To suppress a different color, click the Color Suppression Target picker, then sample a color from the image.



3. To plot the unwanted color on the color chart, click the Plot picker, and then sample a pixel from the area that contains color spill.



In the hue spectrum, a vertical red line indicates the hue that you picked.

Note: You can change the color of the plot line in the Setup controls.

4. On the left of the graph, click the Supp label to select the suppression curve.
5. Click the curve near the plot line and drag it down.



In the image, the target color is suppressed from the indicated hues.

6. To adjust the suppression curve:
• Click the curve to add a control point, then drag the control point to move it.
• When you click a control point, its tangent handles appear. You can drag the handles to adjust the curve. Press Ctrl to break the tangent handle. To unbreak the tangent, press Ctrl and drag again.
• Click the Delete button under the graph to delete selected control points. Click Reset Selected to reset the curve to its default value. Click Reset to reset all the curves.
