I want to fit a button to the whole screen of my apple watch. But there is a lighter red and a dark red like in this picture. 
This is my code: I want the whole screen to have only one color if this is possible. Thanks
Button(action: {
Task {
if (!muteWatch) {
WKInterfaceDevice.current().play(.failure)
}
Task {
await isWorkingSince()
}
}
}, label: {
Text("Stop ".localized() + stopTimeString).padding().frame(
minWidth: 0,
maxWidth: .infinity,
minHeight: 0,
maxHeight: .infinity,
alignment: .topLeading
).background(Color.red)
}).padding().frame(
minWidth: 0,
maxWidth: .infinity,
minHeight: 0,
maxHeight: .infinity,
alignment: .topLeading
).background(Color.red)
