JPanel Background problem....

My code compiles fine, however it doesn't do as its told to put it
lightly.

I'm attempting to set the "JPanel Pork" to be yellow initially. Then
change it via JButtons later.

What am I doing wrong? It wont initially set to yellow.

public class Initial_Displaying extends JFrame
{
    private The_Meat Pork;

    public Initial_Displaying()
    {
           Pork = new The_Meat();
    }

        public void initComponents() throws Exception {

        Pork.setBackground(Color.yellow); // It doesnt set it to
yellow :(

        JPanel content = new JPanel();
        content.setLayout(new BorderLayout(5, 5));
        content.add(Pork, BorderLayout.WEST);

        setContentPane(content);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setTitle("Initial Displaying");
        setLocationRelativeTo(null); // Center window.
        pack();
        setVisible(true);
    }

    static public void main(String[] args) { // Main
entry point
        try {
         Initial_Displaying Test = new Initial_Displaying();
         Test.initComponents();
        }
    catch (Exception e) {
        e.printStackTrace();
        }
    }
}
