title: How can I set custom colors values in a Xaml Value field?
body: <p>So I have some XAML like this:</p>
  
  <pre><code>&lt;Trigger Property="ItemsControl.AlternationIndex" Value="2"&gt;
      &lt;Setter Property="Background" Value="Red"&gt;&lt;/Setter&gt;
  &lt;/Trigger&gt;
  </code></pre>
  
  <p>How can I set the color <code>Red</code>, to something like <code>250 200 150</code>? I tried <code>Color 250 200 150</code>, and <code>250 200 150</code>, but doesn't work. Any ideas?</p>
