[Question] Bind navigation bar background color from viewmodel?

[hypervtechnics]

In general it is possible to influence the color of the navigation bar - I know that. Also how to do it. But this not for a specific page or to a static color. I have the Color in my ViewModel and want the UI to bind to it. Do I need to build something custom or is there a "hacky" way to do so?

Any ideas?
