Change List row background colour programatically

I'm trying to change the background colour of a row in a list based on a value

I have an Int16 value stored in card.owned and I want to change the background if this value is above 0, otherwise use the normal background.

Previously with a table view I could change it with the cellForRowAtIndexPath method, but not sure how to do it with SwiftUI without changing every row

Currently I have

                ForEach(cards) { section in
                    let header: String = nameForSectionHeader(sectionID: section.id)
                    Section(header: Text(header)) {
                        ForEach(section) { card in
                            NavigationLink(destination: CardView(card: card)) {
                                VStack(alignment: .leading) {
                                    if let name = card.name, let id = card.cardID {
                                        Text("\(id) - \(name)")
                                    }
                                    if let set = card.set, let setName = set.name {
                                        Text("Set: \(setName)")
                                    }
                                    if card.owned > 0 {
                                        Text("Owned: \(card.owned)")
                                    }
                                }
                            }
                        }
                    }
                }
                .listRowBackground(lightGreen)
            }
