use a JTextArea (in this example, named jta) and then do something like:

jta.select(0, 5);
jta.setSelectedTextColor(Color.red);
jta.select(5, 10);
jta.setSelectedTextColor(Color.blue);

see my question "Displaying colors in textfield"

one useful link given in my following is

hello bobbit31

your code in not working as required.
when using the method setSelectedTextColor() for the second time,
the color applied in the first call is not being retained.
it is again changing back to the foreground color.

this is because the previous selection is lost when the new text is selected.

you could use a JTextPane to have formatted text... in this case, I set the content type to "text/html":

public class ColorText extends JApplet {
   
    private JTextPane jtp;
       
    public void init()
        {
           jtp = new JTextPane();
           jtp.setContentType("text/html");
           getContentPane().add(jtp);

           jtp.setText("<font color=#0000FF>This is <b>Blue</b></font> <font color=#FF0000>This is <b>Red</b></font>");
     }
}
