Presumably this is a dependency property that should affect rendering? If I change it in an active window, the border doesn't update immediately. I have to switch to a different document window and then switch back to see it.
[Edit] Just looked again at the "Tab Tinting and Flashing" demo. Interestingly, though you do see tinted tabs here, there's no way to change the tint in the demo. If you could, would presumably see the problem I've described.
