如何在WPF TextBlock中更改TextDecoration颜色？

Question

我正在改变TextDecoration这种方式的颜色:

<Grid Background="{x:Null}"
      Margin="10,0,10,0">
    <TextBlock Text="{Binding Value}"
               VerticalAlignment="Center"
               HorizontalAlignment="Center"
               Style="{StaticResource SWMRegularTextBlockStyle}"
               Margin="0"
               FontSize="{DynamicResource RegularFontSize}"
               x:Name="tb" />
        <Line VerticalAlignment="Center"
              HorizontalAlignment="Center"
              Visibility="{Binding InStock, Converter={StaticResource ReverseBooleanToVisiblity}}"
              Stroke="Red"
              Margin="0"
              StrokeThickness="2"
              X1="1"
              Stretch="Fill"
              Width="{Binding ActualWidth, ElementName=tb, UpdateSourceTrigger=PropertyChanged}" />
</Grid>

但是当Text有两条线路失败时.请帮我改变TextDecoration的颜色.提前致谢.

注意:我想要TextBlock不同颜色的前景和透视线.

我想这就是你要找的东西.

<TextBlock Text="{Binding Value}" VerticalAlignment="Center" HorizontalAlignment="Center" Style="{StaticResource  SWMRegularTextBlockStyle}" Margin="0" FontSize="{DynamicResource RegularFontSize}" x:Name="tb" >
   <TextBlock.TextDecorations>
        <TextDecoration Location="Strikethrough">
            <TextDecoration.Pen>
                <Pen Brush="Red" />
            </TextDecoration.Pen>
        </TextDecoration>
    </TextBlock.TextDecorations>
</TextBlock>
