Select column header and first column of a cell in datagridview when selected

I need to change the color of the Header Cell and first column called "col_row" when one or more cells are selected with the mouse like this:

I use this code and its working:

    Private Sub gdv_PatioAcopio_CellStateChanged(sender As Object, e As DataGridViewCellStateChangedEventArgs) Handles gdv_PatioAcopio.CellStateChanged
    If e.Cell.ColumnIndex = 0 Then
        e.Cell.Selected = False
    Else

        If e.Cell.Selected = True Then
            Me.gdv_PatioAcopio.Columns(e.Cell.ColumnIndex).HeaderCell.Style.BackColor = Color.LightBlue
            Me.gdv_PatioAcopio.Rows(e.Cell.RowIndex).Cells("col_row").Style.BackColor = Color.LightBlue
        ElseIf e.Cell.Selected = False Then
            Me.gdv_PatioAcopio.Columns(e.Cell.ColumnIndex).HeaderCell.Style.BackColor = Color.Navy
            Me.gdv_PatioAcopio.Rows(e.Cell.RowIndex).Cells("col_row").Style.BackColor = Color.Navy
        End If

    End If
End Sub

but when i deselect, for example, the third column, the first column changes its color to Color.Navy.

How can i prevent this?

Thanks!
