JUNG: unpicked vertex label color

Question

I can make picked vertex labels red using vertexLabelRenderer declared like this:

DefaultVertexLabelRenderer vertexLabelRenderer=new DefaultVertexLabelRenderer(Color.RED);

How do I change color of unpicked vertex labels. Constructor (see below) only allows defining unpicked vertex labels. Also method setForeground() does not affect the font color.

Here is the JUNG 2.0.1 API document: http://jung.sourceforge.net/site/apidocs/edu/uci/ics/jung/visualization/renderers/DefaultVertexLabelRenderer.html

For anyone still scratching their head here's two simple classes that can change an unpicked vertex/edge label color.

public class MyDefaultVertexLaberRenderer extends DefaultVertexLabelRenderer
{
    protected Color unpickedVertexLabelColor = Color.BLACK;

    public MyDefaultVertexLaberRenderer(Color unpickedVertexLabelColor, Color pickedVertexLabelColor)
    {
        super(pickedVertexLabelColor);
        this.unpickedVertexLabelColor = unpickedVertexLabelColor;
    }

    public <V> Component getVertexLabelRendererComponent(JComponent vv, Object value, Font font, boolean isSelected, V vertex)
    {
        super.setForeground(unpickedVertexLabelColor);
        if (isSelected) setForeground(pickedVertexLabelColor);
        super.setBackground(vv.getBackground());
        if (font != null)
        {
            setFont(font);
        }
        else
        {
            setFont(vv.getFont());
        }
        setIcon(null);
        setBorder(noFocusBorder);
        setValue(value);
        return this;
    }
}

public class MyDefaultEdgeLaberRenderer extends DefaultEdgeLabelRenderer
{
    protected Color unpickedEdgeLabelColor = Color.BLACK;

    public MyDefaultEdgeLaberRenderer(Color unpickedEdgeLabelColor, Color pickedEdgeLabelColor)
    {
        super(pickedEdgeLabelColor);
        this.unpickedEdgeLabelColor = unpickedEdgeLabelColor;
    }

    public <E> Component getEdgeLabelRendererComponent(JComponent vv, Object value, Font font, boolean isSelected, E edge)
    {
        super.setForeground(unpickedEdgeLabelColor);
        if (isSelected) setForeground(pickedEdgeLabelColor);
        super.setBackground(vv.getBackground());

        if (font != null)
        {
            setFont(font);
        }
        else
        {
            setFont(vv.getFont());
        }
        setIcon(null);
        setBorder(noFocusBorder);
        setValue(value);
        return this;
    }
}
