Nimbus L&F trying to change background color of JFormattedTextField with UIManager

SSCCE

import java.awt.EventQueue;
import java.text.NumberFormat;
import java.text.ParseException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JFormattedTextField;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
import javax.swing.WindowConstants;
import javax.swing.event.DocumentEvent;
import javax.swing.event.DocumentListener;
import javax.swing.plaf.ColorUIResource;
import javax.swing.text.Document;
import javax.swing.text.NumberFormatter;

public class Test extends JFrame{

    private JFormattedTextField input, input2;
    private NumberFormatter formatter;


    public Test() {
        formatter = new NumberFormatter(NumberFormat.getNumberInstance());
        input = new JFormattedTextField(formatter);
        input2 = new JFormattedTextField(formatter);


        input.setColumns(4);
        input2.setColumns(4);
        input.setValue(0.0);
        JPanel panel = new JPanel();
        panel.add(input);
        panel.add(input2);

        add(panel);
        pack();
        setVisible(true);
    }

    public static void main(String[] args) {
        try {
            for (UIManager.LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(info.getName())) {
                    UIManager.setLookAndFeel(info.getClassName());
                    UIManager.put("nimbusBase", new ColorUIResource(0, 0, 0));
                    UIManager.put("FormattedTextField.background", Color.RED);
                    UIManager.put("control", new ColorUIResource(153, 76, 0));
                    UIManager.put("textForeground", new ColorUIResource(255, 153, 51));
                    break;
                } }
        } 
        catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
            Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
        }

        EventQueue.invokeLater(new Runnable() {
            public void run() {
                new Test();
            }
        });

    }
}

Problem

Simply put I'm attempting to change the background color of an Enabled JFormattedTextField from the default white to my RGB color. I used the table found here (Link in this blog) to find the appropriate name.

I realize the blog is a little bit outdated (6 years) and Nimbus has been updated a ton since then, so this might be my issue.

How do I go about using UIManager to change the background color of a JFormattedTextField?

Corrected Code

I updated the code above, it works as it should now. The issue was using ColorUIResource instead of just Color.

You have to set this property FormattedTextField.background as found here Nimbus Defaults

Something like this

 UIManager.put("FormattedTextField.background", Color.RED);
