Control the color of individual start menu tiles

For Desktop Apps:

1. Locate the .exe for the tile
   a. Right click the tile icon, and select "Open File Location"
   b. Then right click the shortcut icon, and select "Open File Location" again

2. Create a new file named EXE_Name.VisualElementsManifest.xml and add the following contents:

   <Application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
       <VisualElements BackgroundColor="#666666"
                       ShowNameOnSquare150x150Logo="on"
                       ForegroundText="light"/>
   </Application>

3. Rename the shortcut to refresh the image cache

The previous technique doesn't seem to work on Windows Store / Universal apps, but I can't find anything that does.

There is help on changing tiles that are shortcuts to exe files here:

and there are some utilities that do it for you. Here's one:

It would be nice if this was built in.
