Changing background color of all forms in winform application

I have BaseForm Class like this that is inheriting Form Class

 public partial class BaseForm : Form
 {
    protected override void OnLoad(EventArgs e)
    {
       Color colBackColor =Properties.Settings.Default.FormsBackgroundColor;
       BackColor = colBackColor;
    }
  }

and MainForm class like this which is inheriting BaseForm Class. 

public partial class MainForm : BaseForm
{
    private void button1_Click_1(object sender, EventArgs e)
    {
            ColorDialog colorDlg = new ColorDialog();
            if (colorDlg.ShowDialog() == DialogResult.OK)
            {
                Properties.Settings.Default.FormsBackgroundColor= colorDlg.Color;
                Properties.Settings.Default.Save();
                this.Refresh();
                this.Invalidate();
            }
        }    
 }

When i click button1 on MainForm and choose color from the color dialog. The background color of MainForm doesn't change. What I am doing wrong?

Btw color changes when i re-run the application.

The OnLoad event is only triggered when the form loads, it doesn't get triggered when you click the button. So you need to change the form BackColor in button1_Click_1 also.

if (colorDlg.ShowDialog() == DialogResult.OK)
{
    Properties.Settings.Default.FormsBackgroundColor= colorDlg.Color;
    Properties.Settings.Default.Save();
    this.BackColor = colorDlg.Color;
}
