title: How to change a WinRT ToggleSwitch color?
body: <p>I'm writing a Windows 8 WinRT app in C#, and would like to dynamically change the color of my <code>ToggleSwitch</code>. I'll be having multiple instances of these, and they won't all have the same color. </p>
  
  <p>I tried to create a custom control that inherits from <code>ToggleSwitch</code>, but I quickly learned that I can't do this because <code>ToggleSwitch</code> is a <code>sealed</code> class. My goal was to add a <code>DependencyProperty</code> of type <code>Brush</code>, and then consume that brush through a <code>TemplateBinding</code> in my custom control's <code>Template</code>.</p>
  
  <p>Is there another way of accomplishing this?</p>
