Set text colour of a disabled JSpinner (to make it easier to read)

JSpinner waitHr  = new JSpinner();
waitHr.setEnabled(false);

I have a spinner and I need to prevent the user from editing it temporarily. The problem is, when the spinner is disabled, it's text colour makes it very hard to read, which is not acceptable in this case. I noticed that you can do this with JTextFields:

 JTextField txtTest   = new JTextField();
 txtTest.setDisabledTextColor(Color.BLACK);

Is there anything similar that can be used for a JSpinner?

you can play with that as you want

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

public class InactiveBackgroundTest {

    public JComponent makeUI() {
        JSpinner s0 = new JSpinner();
        s0.setPreferredSize(new Dimension(100, 20));
        s0.setEnabled(false);
        UIManager.put("FormattedTextField.inactiveBackground", Color.RED);
        JSpinner s1 = new JSpinner();
        s1.setEnabled(false);
        s1.setPreferredSize(new Dimension(100, 20));
        JSpinner s2 = new JSpinner();
        s2.setEnabled(false);
        s2.setPreferredSize(new Dimension(100, 20));
        JTextField field = ((JSpinner.NumberEditor) s2.getEditor()).getTextField();
        field.setEditable(false);
        field.setBackground(UIManager.getColor("FormattedTextField.background"));
        JSpinner s3 = new JSpinner();
        s3.setPreferredSize(new Dimension(100, 20));
        s3.setEnabled(false);
        s3.setBorder(null);

You can use the getTextField() method of JSpinner.DefaultEditor.
