if you have the form, post the code you have.
and whether you want to do this client side (in javascript) or server side (if you post the code language will be obvious, if you don't, well, you probably want to let someone know if you're a VB or C# coder.)

ok, in page load you need to add this then.
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            TextBox1.BackColor = Drawing.Color.Red
        End If
    End Sub

and in the page, add Checked="true" to red radio button.

and here is one of the radio button event handlers, hopefully you can do the other two...
    Protected Sub GreenRadioButton_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GreenRadioButton.CheckedChanged
        TextBox1.BackColor = Drawing.Color.Green
    End Sub

also, you have the text mixed up on the green and red options, the greenradiobutton, says red, and vice/versa.
