The problem is, I have changed the background color property to the standard black [0, 0, 0] color. The problem is, at runtime, the color isn't actually changed, it stays the default kinda greyish color. Any ideas?

I set the background of the form, not just 1 component. I don't have another form at the moment, and only 1 button on my current form, so it's pretty difficult (I believe) for NetBeans to screw this up.

java

private void initComponents() 
{
        jButton1 = new javax.swing.JButton();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        setTitle("Login");
        setAlwaysOnTop(true);
        setBackground(new java.awt.Color(0, 0, 0));
        setCursor(new java.awt.Cursor(java.awt.Cursor.DEFAULT_CURSOR));
        setResizable(false);

        jButton1.setText("Login");
        jButton1.addActionListener(new java.awt.event.ActionListener() 
        {
            public void actionPerformed(java.awt.event.ActionEvent evt) 
            {
                jButton1ActionPerformed(evt);
            }
        });

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addGap(142, 142, 142)
                .addComponent(jButton1)
                .addContainerGap(149, Short.MAX_VALUE))
        );
        layout.setVerticalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(javax.swing.GroupLayout.Alignment.TRAILING, layout.createSequentialGroup()
                .addContainerGap(167, Short.MAX_VALUE)
                .addComponent(jButton1)
                .addGap(41, 41, 41))
        );

        jButton1.getAccessibleContext().setAccessibleName(null);

        pack();
    }// </editor-fold>

The setBackground(new java.awt.Color(0, 0, 0)) command is correct, since it's just doing this to the form...

EDIT: ARGH, I hate the way NetBeans generates code. (I just switched the brace locations.)

Since you would THINK that NetBeans would be smart enough to do that on it's own since I set the property on the form the same as I did in the code. java private LoginForm() { initComponents(); getContentPane().setBackground(java.awt.Color.black); } I still don't know why it doesnt do that automatically...But thanks all the same!

The JFrame has a background color, but the entire contents of a JFrame are covered by the content pane, so you need to change to color of the content pane, not the JFrame. Otherwise the content pane simply covers the JFrame and there is no change.
