title: How do I know which systemcolors to use for different controls If I want default classic Window look?
body: <p><strong>In my DefaultTheme.xaml File I have only set my colors</strong></p>
  <pre><code>&lt;SolidColorBrush x:Key=&quot;CheckboxForegroundColor&quot;                Color=&quot;Black&quot;/&gt;
      &lt;SolidColorBrush x:Key=&quot;CheckboxBackgroundColor&quot;                Color=&quot;{DynamicResource {x:Static SystemColors.WindowColorKey}}&quot;/&gt;
      &lt;SolidColorBrush x:Key=&quot;CheckboxBorderbrushColor&quot;               Color=&quot;{DynamicResource {x:Static SystemColors.WindowColorKey}}&quot;/&gt;
  </code></pre>
  <p><strong>In my ColorTheme.xaml I have done the same but different colors</strong></p>
  <pre><code>   &lt;SolidColorBrush x:Key=&quot;CheckboxForegroundColor&quot;                Color=&quot;#FFFFFFFF&quot;/&gt;
       &lt;SolidColorBrush x:Key=&quot;CheckboxBackgroundColor&quot;                Color=&quot;#FF2d2d30&quot;/&gt;
  &lt;SolidColorBrush x:Key=&quot;CheckboxBorderbrushColor&quot;               Color=&quot;#FFCC1517&quot;/&gt;
  </code></pre>
  <p><strong>In my App.xaml</strong></p>
  <pre><code>&lt;Setter Property=&quot;Foreground&quot;               Value=&quot;{DynamicResource CheckboxForegroundColor}&quot; /&gt;
                      &lt;Setter Property=&quot;Background&quot;               Value=&quot;{DynamicResource CheckboxBackgroundColor}&quot; /&gt;
                      &lt;Setter Property=&quot;BorderBrush&quot;              Value=&quot;{DynamicResource CheckboxBorderbrushColor}&quot;/&gt;
  </code></pre>
  <p>Changing themes at runtime works fine and my ColorTheme works fine also. But my question is how do I know which systemcolors to use for example Button.Foreground and Button.Background to get the windows Classic look? There are so many Systemcolors I get confused and don't know which one to use for different controls. I have set all my colors to WindowsColorKey in my Default.xaml but seems that it is the wrong way to do it because my application becomes white.</p>
