I'm not sure it's the best way, but the approach shown below may offer a 
temporary workaround. IIUC, disabled isn't just a color; it's a 
platform specific implementation intended to be visibly distinct from 
enabled text, irrespective of color.

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

public class test extends JFrame {

    private static final String disabled = "MenuItem.disabledForeground";
    private static final Color disColor = (Color) UIManager.get(disabled);

    public test() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JMenuBar mb = new JMenuBar();
        setJMenuBar(mb);
        JMenu menu = new JMenu("test");
        mb.add(menu);

        JMenuItem mi = new JMenuItem("This is default disabled");
        mi.setEnabled(false);
        menu.add(mi);
        UIManager.put(disabled, Color.red);
        mi = new JMenuItem("This is disabled red");
        mi.setEnabled(false);
        menu.add(mi);
        UIManager.put(disabled, disColor);
        mi = new JMenuItem("Default restored");
        mi.setEnabled(false);
        menu.add(mi);

        JPanel p = new JPanel();
        p.setPreferredSize(new Dimension(100, 100));
        add(p);

        pack();
        setVisible(true);
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                new test();
            }
        });
    }
}

Cf. the JTextComponent, which has setDisabledTextColor():
