In a WPF DataGrid, all cell-related design needs to be set as the Column's ElementStyle, which overrides the foreground set in your Grid. Try the following:

In your XAML resources:

<Style x:Key="BlackCellStyle" TargetType="{x:Type TextBlock}">
    <Setter Property="Foreground" Value="Black" />
</Style>

In your AutoGeneratingColumn handler:

private void dg_AutoGeneratingColumn(object sender, System.Windows.Controls.DataGridAutoGeneratingColumnEventArgs e)
{
  string str = e.PropertyName;
  int num = int.Parse(e.PropertyName);
  e.Column.Header = "C" + (num + 1).ToString();
  e.Column.ElementStyle = FindResource("BlackCellStyle") as Style;
}

This will apply the foreground directly to your cells
