title: ModernUI : Apply current theme to UserControl BackGround
body: <p>How can I apply the ModernUI <em>background</em> color (Dark/Light) to a UserControl? I successfully retrieved and applied the <em>accent</em> color, but I can't figure out how to apply the Dark/Light background color. By default, my UserControl's background is transparent.</p>
  
  <p>Here is how I applied the <em>accent</em> color (this works):</p>
  
  <pre><code>&lt;UserControl x:Class="GenkaiModern.Pages.DetailView"
               xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
               xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
               xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
               xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
               xmlns:local="clr-namespace:GenkaiModern.Pages" 
                xmlns:mui="http://firstfloorsoftware.com/ModernUI"
               mc:Ignorable="d" 
  
               d:DesignHeight="399.533" d:DesignWidth="751.402" Width="720" Height="350" Background="{DynamicResource Accent}" &gt;
  &lt;/UserControl&gt;
  </code></pre>
