title: WPF Label appears off white instead of white

  <p>Some things have been whited out for privacy. The About is how I would like the rest of the labels to look, and they all have the same styling yet they render differently. The Connections/Policies appear to be an off-white (They are labels) and the rest of the controls appear white (they are buttons)</p>
  
  <p>Nowhere in any style am I setting the color to this off-white, the label is set to have a white foreground and a black drop shadow and it appears gray instead of white. A similar control, a button, that has the exact same styling does not have this off-white colour and appears crisp and white.</p>
  
  <p>The label is placed inside of the second row of a column, inside of a stack panel that is inside of another stack panel. When I place the label outside of the stack panels into the base grid row then this graying does not occur. I am new to WPF and cannot find any sort of solution.
  Below is a snippet of the label xaml in question with the extra/irrelevant infomation removed such as column definitions and unrelated controls.</p>
  
  <pre><code>&lt;Grid&gt;
      &lt;ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto"&gt;                         
          &lt;StackPanel Orientation="Horizontal" Grid.Row="1" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="5"&gt;
              &lt;StackPanel HorizontalAlignment="Left" VerticalAlignment="Center"&gt;
                  &lt;Label Content="Connections" Foreground="White" VerticalContentAlignment="Bottom" Background="{x:Null}"  VerticalAlignment="Bottom" Padding="0" HorizontalAlignment="Left" FontSize="14" Margin="0,5,0,0"&gt;
                      &lt;Label.Effect&gt;
                          &lt;DropShadowEffect ShadowDepth="0" BlurRadius="3" /&gt;
                      &lt;/Label.Effect&gt;
                  &lt;/Label&gt;
              &lt;/StackPanel&gt;
          &lt;/StackPanel&gt;
      &lt;/ScrollViewer&gt;
  &lt;/Grid&gt;
