With the following code, I can conditionally assign different colors to navigationTitle text.

init() {
    //Use this color when UINavigationBar shows large title (unscrolled)
    UINavigationBar.appearance().largeTitleTextAttributes = [.foregroundColor: UIColor.blue]

    //Use this color when UINavigationBar shows inline title (scrolled down
    UINavigationBar.appearance().titleTextAttributes = [.foregroundColor: UIColor.green]
}

And I wanted to do the same for toolbar items, but couldn't figure out how.

I can set the "general" color of toolbar items like below, but I'm having trouble conditionally assigning different colors to toolbar items depending on if the NavigationBar is in largeTitle mode or inline title mode. Any leads would be helpful, thank you!

ToolbarItem(placement: .navigationBarTrailing) {
    HStack(spacing: 20) {
        Button {
          // button action
        } label: {
            Image(systemName: "location.circle.fill")
                .foregroundColor(.green)
        }
        Button {
            // button action
        } label: {
            Image(systemName: "gear")
                .foregroundColor(.green)
        }
    }
}
