I noticed with the first big Windows 10 update that some desktop apps have tiles in a different color than the one I have for accent color, like Firefox, which has a dark-gray tile color:
However, not all apps have this, and use the default accent color, like Blender.
I wonder if this change is similar to what Windows 8.1 did with an updated Start screen, in which you could set the color of a desktop app tile via XML.
I'm a novice with the Windows platforms in C#, and I think it would be nice to implement in my programs a more customized tile on the start screen, but I don't know how.
