title: TextColor of Xamarin.Forms SearchBar
body: <p>I have a Xamarin.Forms SearchBar on a StackLayout with a dark background color.</p>
  
  <p>By default the input field is dark as well, probably due to a transparent background. To modify the search bar background color there is a <code>BackgroundColor</code> property. (In the example below I set it to dark gray.)</p>
  
  <p>But how to adjust the text color? There is no such property. And even with a custom search bar renderer I don't find a solution.</p>
  
  <p>This is how it looks with just the placeholder:</p>

  <p>...and with some input (black "Hello world!" on a pretty dark background):</p>
