title: windows phone light theme making textboxes invisible
body: <p>I want to app background to black only so i put black background image to all the pages grids..</p>
  
  <p>now the problem is when phone is running on dark theme everything is perfect but if it is running on light theme then all the things (most of them) are invisible now because when there is light theme phone changes the colors  to go dark &amp; because of black background its invisible</p>
  
  <pre><code>so I set the manual colors to all the things which makes most of the things visible now but still when i click on textbox it gets dark
  </code></pre>
  
  <p>is there any solution where i can keep my black background &amp; still have everything visible in light theme?</p>
