api/javax_swing/plaf/basic/BasicColorChooserUI/index.html#protected[BasicColorChooserUI2005]
api/javax_swing/plaf/basic/BasicColorChooserUI/index.html#public[BasicColorChooserUI0001]

Following code demonstates the problem:

import java.awt.*;
import javax.swing.*;

public class test {
    public static void main(String argv[]) {
        JColorChooser colorChooser = new JColorChooser();
        colorChooser.getPreviewPanel().getForeground();
    }
}
