How can I change the background Color of a navigation view?

I'm currently creating the sidebar for my app and now I am facing the problem of how I can change the background Color of my navigation view without affecting the background of the other views.
I've tried it like this:

Code Block init(){ 	UITableView.appearance().backgroundColor = UIColor.secondarySystemBackground}

That works but now all of my list backgrounds have this color, which a don't want.


And if I try it like this, it doesn't change at all:

Code Block  ZStack{    Color.red    List{        VStack{            NavigationLink(destination: ColorMenu()){                Label("Colors", systemImage: "square.grid.2x2.fill").accentColor(Color("Colory"))            }        }    }}

So my question is if there is a way to change the background Color without affecting all the other views?

Thanks in advance

    var body: some View {
 
        NavigationView {
            ZStack {
                Color.purple
                    .ignoresSafeArea()
                // Usual content
            }
    }
