Calling setBackground-methods of the TextField-Objects and the TextArea-Objects
has no effect when they are set not editable: The preset background colour
(here: gray) is set, whatever Color object you specify.

Try following source code:

import java.awt.Font;
import java.awt.Frame;
import java.awt.GridLayout;
import java.awt.TextArea;
import java.awt.TextField;

class Tf_ta_test extends Frame {
  TextField tfEditable;
  TextField tfNotEditable;
  TextArea taEditable;
  TextArea taNotEditable;

  Tf_ta_test() {
    this.setTitle("TextField/-Area-Test");
    this.setFont(new Font("SansSerif",Font.PLAIN,12));
    this.setBackground(Color.lightGray);
    this.setLayout(new GridLayout(4,1));
    this.addWindowListener(new FrameListener(this));
    tfEditable = new TextField("Dieses Feld ist editierbar!");
    tfEditable.setEditable(true);
    tfEditable.setForeground(Color.blue);
    tfEditable.setBackground(Color.orange);
    tfNotEditable = new TextField("Dieses Feld ist nicht editierbar!");
    tfNotEditable.setEditable(false);
    tfNotEditable.setForeground(Color.blue);
