Summary0002194: Black Drop Shadows Rendered Transparent in Unity
Description

This XAML
<DropShadowEffect BlurRadius="50" Direction="0" ShadowDepth="0" Opacity="1" Color="Black"/> // OR
<DropShadowEffect BlurRadius="50" Direction="0" ShadowDepth="0" Opacity="1" Color="#110000/>
renders as result image HEX110000.png.

This XAML
<DropShadowEffect BlurRadius="50" Direction="0" ShadowDepth="0" Opacity="1" Color="#FF0000/>
renders as result image HEXFF0000.png.

Is there something I should be doing to render shadows as black?

In my tests the drop shadow seems to work the same as in WPF. I even tried with Photoshop and the results are very similar.

What is happening is that BlurRadius is very big and it mixes with the background, but there is a difference if you remove the shadow. If you use a white background you can clearly see that there is a shadow there.
When using red as shadow it stands out more because you don't expect that color around the text and it is very different from the background.

If you need a bit more of contrast with the background in your texts, you can always use the text stroke:

<TextBlock noesis:Stroke="#80000000" noesis:StrokeThickness="2.5" Foreground="White" .../>
