Awt.geom shape as Icon?

Question

I want to use a geometric shape (specifically, a small circle) the icon for a JToggleButton. I can't use a static image as I need to be able to change the color of the icon. Is there any class that implements the Icon interface and has the methods of the awt.geom classes?
Thanks

Or like this?
import java.awt.*;
import java.awt.geom.AffineTransform;
import java.awt.geom.Ellipse2D;
import javax.swing.*;
public class ShapeIcon implements Icon {
    private final Paint paint;
    private final Shape shape;
    public ShapeIcon(Paint paint, Shape shape) {
        this.paint = paint;
        this.shape = shape;
    @Override
    public int getIconHeight() {
        return shape.getBounds().height;
    @Override
    public int getIconWidth() {
        return shape.getBounds().width;
    @Override
    public void paintIcon(Component c, Graphics g, int x, int y) {
        Graphics2D g2 = ((Graphics2D) g);
        g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                RenderingHints.VALUE_ANTIALIAS_ON);
        g2.setPaint(paint);
        g2.fill(AffineTransform.getTranslateInstance(x, y).createTransformedShape(shape));
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                JLabel label = new JLabel(new ShapeIcon(
                        Color.RED, new Ellipse2D.Double(0, 0, 32, 32)));
                label.setBorder(BorderFactory.createLineBorder(Color.BLUE));
                JOptionPane.showMessageDialog(null, label);
}
