 <p>I've found a solution.</p> <p>I can apply system theme for that single element in the resource, something like this:</p> <pre><code>&lt;ResourceDictionary&gt; &lt;ResourceDictionary.MergedDictionaries&gt; &lt;ResourceDictionary Source="/PresentationFramework.Aero;V3.0.0.0;31bf3856ad364e35;component\themes/aero.normalcolor.xaml" /&gt; &lt;/ResourceDictionary.MergedDictionaries&gt; &lt;/ResourceDictionary&gt; </code></pre>
