    I’ve tried using .toolbarBackground(.hidden, for: .bottomBar), but it doesn't seem to work. How can I remove the background color of the toolbar in the root view? 

    var body: some Scene {
    WindowGroup {
       RootView()
    }
}

    struct RootView: View {
   let columns = [
      GridItem(.flexible(), spacing: 0),
      GridItem(.flexible(), spacing: 0)
   ]
   
   var body: some View {
      ScrollView{
         ZStack{
            cardStack()
         }
         .frame(maxWidth: .infinity, maxHeight: .infinity)
      }
      .background(Color("BA3D4E"))
      .modifier(CustomToolsBar())
   }
}

    struct CustomToolsBar: ViewModifier {
   func body(content: Content) -> some View {
      content
         .toolbar {
            ToolbarItemGroup(placement: .bottomBar) {
               Text("Yesterday")
               Spacer()
               Text("+")
               Spacer()
               Text("Tomorrow")
            }
         }
         .toolbarBackground(.hidden, for: .bottomBar)
   }
}

    Like most .toolbar related modifiers, it needs to be in a NavigationStack for it to actually work:

    import SwiftUI

struct RootView: View {
    
    var body: some View {
        NavigationStack {
            ScrollView {
                
                ForEach(1...10, id: \.self) { number in
                    Text("Row \(number)")
                        .frame(maxWidth: .infinity, maxHeight: .infinity)
                        .padding()
                        .background(.regularMaterial.opacity(0.5), in: Capsule())
                        .padding(.horizontal)
                }
            }
            .navigationTitle("Root view")
            .toolbarTitleDisplayMode(.inline)
            .background(Color(red: 0.733, green: 0.239, blue: 0.302))
            .modifier(CustomToolsBar())
        }
        .foregroundStyle(.white)
    }
}

struct CustomToolsBar: ViewModifier {
    func body(content: Content) -> some View {
        content
            .toolbar {
                ToolbarItemGroup(placement: .bottomBar) {
                    Text("Yesterday")
                    Spacer()
                    Text("+")
                    Spacer()
                    Text("Tomorrow")
                }
            }
            .toolbarBackground(.hidden, for: .bottomBar)
    }
}

#Preview {
    RootView()
}

    I couldn't find a way to hide the native toolbar background either.

    However, if you don't want the toolbar background to be shown, there probably isn't much point in adding your custom toolbar using the modifier .toolbar. You might as well add it using .safeAreaInset instead:

    struct CustomToolsBar: ViewModifier {
    func body(content: Content) -> some View {
        content
            .safeAreaInset(edge: .bottom) {
                HStack {
                    Text("Yesterday")
                    Spacer()
                    Text("+")
                    Spacer()
                    Text("Tomorrow")
                }
                .padding()
            }
    }
}
