WPF：如何为上下文菜单实现Blend的Dark主题

Question

我在我的App.xaml中添加了这个xaml：

<Style TargetType="{x:Type ContextMenu}">
   <Setter Property="Background" Value="{StaticResource ShadeBrush}" />
   <Setter Property="BorderBrush" Value="{StaticResource ShadeBrush}" />
   <Setter Property="Foreground" Value="White" />
</Style>    

这让我走向黑暗主题的大部分方向...... 如何使用菜单项解决此问题：

我怀疑我需要修改menuitem的样式或模板 感谢。

更新：使用Snoop（Andy提到，谢谢），我在选择白色矩形时发现这一点：

对于接下来来到这里的人，我通过设置模板解决了这个问题：

<Style TargetType="{x:Type ContextMenu}">
    <Setter Property="Background" Value="{StaticResource ShadeBrush}" />
    <Setter Property="BorderBrush" Value="{StaticResource ShadeBrush}" />
    <Setter Property="Foreground" Value="White" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ContextMenu}">
                <Border Uid="Border_93">
                    <Border.Style>
                        <Style TargetType="{x:Type Border}">
                            <Setter Property="Tag" 
                    Value="{DynamicResource 
                        {x:Static SystemParameters.DropShadowKey}}"/>
                            <Style.Triggers>
                                <DataTrigger 
                            Binding="{Binding Tag, 
                                RelativeSource={RelativeSource Self}}" 
                            Value="True">
                                    <Setter Property="Background" 
                            Value="Transparent"/>
                                    <Setter Property="Padding" 
                            Value="0,0,5,5"/>
                                    <Setter Property="Effect">
