to keep the radiobuttons unchecked in form load

Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged

        Me.BackColor = Color.Black

    End Sub

    Private Sub RadioButton2_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton2.CheckedChanged

        Me.BackColor = Color.LightGreen

    End Sub

    Private Sub RadioButton3_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton3.CheckedChanged

        Me.BackColor = Color.OrangeRed

    End Sub

    Private Sub Form5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        RadioButton1.Checked = False

        RadioButton2.Checked = False

        RadioButton3.Checked = False

    End Sub

but when i try to debug the form is loading with the first radiobutton checked and also with the backcolor of the event.

i want my form to be plain when it loads and only it should change when i click radiobutton..

thanks
