Solution for Windows phone RT app: In OnLaunched method of App.xaml add below code:

     var statusBar = Windows.UI.ViewManagement.StatusBar.GetForCurrentView();
     statusBar.BackgroundColor = Colors.Green;
     statusBar.ForegroundColor = Colors.Red;
     statusBar.BackgroundOpacity = 1;

     statusBar.ProgressIndicator.Text = "Some text";
     statusBar.ProgressIndicator.ShowAsync();

For WP Silverlight App: You may need to define style in App.xaml under tag

 <Style x:Key="SystemTrayStyle" TargetType="phone:PhoneApplicationPage">
        <Setter Property="shell:SystemTray.BackgroundColor" Value="Red" />
        <Setter Property="shell:SystemTray.ForegroundColor" Value="Green" />
    </Style>

And on individual xaml page you can add this style

<phone:PhoneApplicationPage
shell:SystemTray.IsVisible="True"
Style="{StaticResource SystemTrayStyle}">
