Example: Using the Limit Effect Controls of the Color Corrector Filter to Change a Specific Color

This example shows you how to use the Limit Effect controls of the Color Corrector filter to selectively change the color of a man’s pants from red to blue, without changing the color of anything else in the frame.

To use the Limit Effect controls to change a specific color
  1. With the Color Corrector filter already applied, click the Select Color eyedropper.

    Figure. Select Color eyedropper.
  2. In the Canvas, click the eyedropper in the man’s red pants to select a primary key color.

    Try to pick a color value that lies somewhere between the brightest and darkest areas to which you’re trying to limit the effect.

    Now, you’ll make a hue adjustment so that you can see the area you’re trying to isolate.

  3. To make the pants pink, rotate the Hue control toward magenta.

    You can also use the View Final/Matte/Source button (the key) to view the key itself as a grayscale image while you make changes. Adjusting the Limit Effect controls while viewing the color correction effect is more interactive.

  4. To fine-tune the effect, move the top two handles of the Color Range control outward to include more of the yellow area of the picture.

    You can also widen the bottom handles to increase the tolerance of the selected color range and include a greater range of color at the edge of the primary key color.

    If you need to readjust the range of hues between these handles, drag in the color gradient and move the range of hues left or right in relation to the Color Range handles.

    Now that you’ve selected the main key color range, you can make adjustments to the luma to increase the amount of the picture that is affected by the key.

  5. Move the top handles in the Luma control to select a primary luma range to affect, then adjust the bottom handles to adjust the tolerance.

  6. Finally, make similar adjustments to the Saturation control to further increase the range. You can even include the edges of the yellow shirt.

    Note: As you work, changes made to one control may change the effectiveness of the others. For example, a different saturation range may work better if adjustments are also made to the Luma control.
