Java SE (Java Platform, Standard Edition)

I am in the middle of developing a small program that allows the user to select a color from a list and then it will display an example of the color along with the RGB codes. I have the program working fine but I am looking for a more sufficient way. Does anyone know how to get the RGB codes from the color name (maybe the getColorComponet() method?) so I can get rid of having to type in the colors codes? If you do, can you please show me how because I am a complete noob to this and I love it but I need some help. Thanks guys!

Here is my code:

//ColorSelector.java


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


class ColorSelector extends JFrame implements ListSelectionListener {
        //Containers
        JPanel mainPanel;
        JPanel innerPanel;
        JPanel northPanel;
        //Components
 JLabel instructions; 
 JTextField colorCode;   //displays RGB codes of color
        String[] colorChoices = {"Red",  //color names in list
    "Blue",
    "Green",
    "Black",
    "Cyan",
    "Magenta",
    "Gray",
    "Light Gray",
    "Dark Gray",
    "Orange",
    "Pink",
    "White",
    "Yellow"};


 public ColorSelector(){
  setTitle("Grant Vinson's Color Selector");
  setSize(400,350);


  addWindowListener(new WindowAdapter() {
   public void windowClosing(WindowEvent e) {
    System.exit(0);
   }
  });


  instructions = new JLabel("Select your favorite color");
  colorCode = new JTextField("Please select a color");


  JList colors = new JList(colorChoices);
  colors.addListSelectionListener(this);


  innerPanel = new JPanel();
  innerPanel.add(colors);
  innerPanel.setBackground(Color.white);


  northPanel = new JPanel();
  northPanel.setBackground(Color.white);
  northPanel.add(instructions);


  mainPanel = new JPanel();
  mainPanel.setLayout(new BorderLayout());
  mainPanel.setBackground(Color.white);


  mainPanel.add(northPanel,"North");
  mainPanel.add(innerPanel,"West");
  mainPanel.add(colorCode,"South");
  getContentPane().add(mainPanel);
 }


 public void valueChanged(ListSelectionEvent e) {
  JList source = (JList)e.getSource();

  Object[] values = source.getSelectedValues();


  for(int x=0;x<values.length;x++)
  {
                    String chosenColor = (String)values[x];

                    if (chosenColor == "Red")
                    {
