To change DataGridRow Foreground color when mouse is over, you have to use style trigger. This is an example of how to do it. In this example I set the Foreground color to white to make it more visible.

XAML:

<Window x:Class="PocWpf.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.Resources>
            <Style TargetType="{x:Type DataGridRow}" x:Key="GreenForegroundStyle">
                <Style.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter Property="Foreground" Value="White" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Grid.Resources>
        <DataGrid x:Name="dgTest" AutoGenerateColumns="True" RowStyle="{StaticResource GreenForegroundStyle}">

        </DataGrid>
    </Grid>
</Window>

Code behind:

namespace PocWpf
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            this.Loaded += new RoutedEventHandler(MainWindow_Loaded);
        }

        void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            var list = new List<string>();

            list.Add("A");
            list.Add("A");
            list.Add("A");
            list.Add("A");
            list.Add("A");
            list.Add("A");
            list.Add("A");
            list.Add("A");
            list.Add("A");
            list.Add("A");

            this.dgTest.ItemsSource = list;
        }
    }
}

This is the result:
