Windows Phone 8 development - Change icon color depending on phone background

Smart way to change icon color:

<Border x:Name="Wifi" Width="76" Height="76" 
                    HorizontalAlignment="Right" VerticalAlignment="Bottom" 
                    Background="{StaticResource PhoneForegroundBrush}"                                Margin="0,0,360,82" Tap="WhenTappedWifi" >
        <Border.OpacityMask>
             <ImageBrush ImageSource="Assets/Tiles/Custom/wifi.png" />
        </Border.OpacityMask>
</Border>

Windows Phone 8 - Navigate To and From Page

I needed a solution to change the state of an element when going back to the page where it was.
I tried the Loaded event, but this did not do the trick.
What worked was Page Navigation:

protected override void OnNavigatedFrom(System.Windows.Navigation.NavigationEventArgs e)
{
    base.OnNavigatedFrom(e);

    // code
}

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
    base.OnNavigatedTo(e);

    // code
}
