C# XAML deactivate highlighting on tap

Question

I want to deactivate the blue highlight on Windows Phone 8.1 that I get whenever I click a Button or ListBox Item. Like everything that is transparent is blue.

The Button is only displayed as a clickable image:

<Button Content="" BorderBrush="Transparent" Foreground="Transparent" HorizontalAlignment="Center" Margin="145,-0.5,146,0" VerticalAlignment="Top" Height="120" Click="btn_Lock" Grid.Row="1">
   <Button.Background>
       <ImageBrush Stretch="Uniform" ImageSource="Assets/safe_icon.png"/>
   </Button.Background>
</Button>

And the ImageBox Items are normal items as well and have a blue background where the rest is transparent when clicking and white when selected. This should not be visible but transparent as well.

Thank you in advance

To make the change to the button control you need to change its style below is an example of changing the style of a button from the themebackgroundcolor to pink...

XAML Styles is a complicated subject ... http://msdn.microsoft.com/en-us/expression/dd279541.aspx

I would recommend watching blend for developers from plural site as well to master this subject

In the below example the buttons color is changed from the default color to pink when it is clicked on...
