For completeness:

If you really intend to change the color at runtime, disregarding MVVM you can for instance use DataGrid_LoadingRow, check for it's DataContext (in this case a DataRowView) and go on from there:

// Changes beeing made to the entire row in this case
private void DgModules_LoadingRow(object sender, DataGridRowEventArgs e)
{
    DataGridRow gridRow = e.Row;
    DataRow row = (gridRow.DataContext as DataRowView).Row;
    switch (row.RowState)
    {
        case DataRowState.Added:
            gridRow.Background = new SolidColorBrush(Colors.Green);
            break;
        case DataRowState.Modified:
            gridRow.Background = new SolidColorBrush(Colors.Yellow);
            break;
        case DataRowState.Deleted:
            gridRow.Background = new SolidColorBrush(Colors.Red);
            break;
    }
}

If you wanna approach this actually using MVVM, go for this solution.
