try this:

So let me get this right, if the text box is EMPTY, change the color for the next time.

ok try this:

    Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        If TextBox1.Text = "" Then

            If TextBox1.ForeColor = Color.Red Then
                TextBox1.ForeColor = Color.Green
            Else
                TextBox1.ForeColor = Color.Red
            End If
        End If
