Metro App ListView SelectedItem Selected VisualState - windows-runtime

Question

I have a Metro App with a ListView that contains this definition:
<ListView Grid.Row="0" x:Name="lv" CanDragItems="True" CanReorderItems="True" IsTabStop="True" SelectionMode="Extended" VirtualizingStackPanel.VirtualizationMode="Recycling">
<ListView.ItemTemplate>
<DataTemplate>
<Grid Width="{Binding ElementName=lv, Path=ActualWidth}">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="65"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" x:Name="tb1" Foreground="{StaticResource SecondaryColourBrush}" HorizontalAlignment="Stretch"/>
<TextBlock Grid.Column="4" x:Name="tb2" Foreground="{StaticResource SecondaryColourBrush}" HorizontalAlignment="Right"/>
</Grid>
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="65"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" x:Name="tb3" Foreground="{StaticResource QuadColourBrush}" HorizontalAlignment="Stretch" TextTrimming="WordEllipsis"/>
<TextBlock Grid.Column="1" x:Name="tb4" Foreground="{StaticResource QuadColourBrush}" HorizontalAlignment="Right"/>
</Grid>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
When the ListView has an item selected, I want to change the Foreground of tb1 and tb2 ONLY to White. How do I go about doing this?
I tried overriding Themed Brushes and VisualStateGroup SelectionStates for Selected, which hasn't helped. A working code example would be appreciated.

Finally RESOLVED this, thanks to this article for giving me the idea:
http://blog.davemdavis.net/2012/11/12/controlling-the-datatemplate/
Created a BooleanToColourConverter
public sealed class BooleanToColourConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, string language)
{
return (value is bool && (bool)value) ? AppResources.TertiaryColourBrush : AppResources.PrimaryColourBrush;
}
public object ConvertBack(object value, Type targetType, object parameter, string language)
{
return value is SolidColorBrush && ((SolidColorBrush)value).Color == AppResources.TertiaryColourBrush.Color;
}
}
Added this in App.xaml
<common:BooleanToColourConverter x:Key="BooleanToColourConverter"/>
Then used it like this:
Foreground="{Binding Tag, Converter={StaticResource BooleanToColourConverter}, Mode=TwoWay, RelativeSource={RelativeSource Mode=TemplatedParent}}"
