For List  All SwiftUI s Lists are backed by a UITableViewin iOS  so you need to change the background color of the tableView  But since Color and UIColor values are slightly different  you can get rid of the UIColor  struct ContentView   View       init            UITableView appearance   backgroundColor    clear                var body  some View           List               Section header  Text  quot First Section quot                      Text  quot First Cell quot                             Section header  Text  quot Second Section quot                      Text  quot First Cell quot                                    background Color yellow           Now you can use Any background  including all Colors  you want  Also First look at this result   As you can see  you can set the color of each element in the View hierarchy like this  struct ContentView  View            init            UINavigationBar appearance   backgroundColor    green            For other NavigationBar changes  look here  https   stackoverflow com a 57509555 5623035             var body  some View           ZStack               Color yellow             NavigationView                   ZStack                       Color blue                     Text  quot Some text quot                                   background Color red                     And the first one is window  window backgroundColor    magenta  The very common issue is we can not remove the background color of SwiftUI s HostingViewController  yet   so we can t see some of the views like navigationView through the views hierarchy  You should wait for the API or try to fake those views  not recommended

Screen s Background Color  As of Xcode Version 12  I m not sure if the original poster meant the background color of the entire screen or of individual views  So I ll just add this answer which is to set the entire screen s background color  Using ZStack var body  some View       ZStack               Color purple                  ignoresSafeArea                               Your other content here                Other layers will respect the safe area edges          I added  ignoresSafeArea   otherwise  it will stop at safe area margins  Using Overlay Modifier var body  some View       Color purple          ignoresSafeArea  vertical     Ignore just for the color          overlay              VStack spacing  20                    Text  quot Overlay quot   font  largeTitle                  Text  quot Example quot   font  title  foregroundColor  white                Note  It s important to keep the  ignoresSafeArea on just the color so your main content isn t ignoring the safe area edges too
