Change navigation header background color

Paste this in your targeted screen

static navigationOptions = ({ navigation }) => {
   return {
      title: 'Screen Title',
      headerTintColor: 'royalblue',
      headerStyle: {
         backgroundColor: '#fff'
      }
   }
}

This should work:

static navigationOptions = () => ({
    title: 'My App',
    headerTintColor: Colors.DarkBlue,
    headerStyle: {
      backgroundColor: 'red'
    },
    headerLeft:
      <HeaderBarItem to='InfoScreen' title='App info' />,
    headerRight:
      <HeaderBarItem to='FeedbackScreen' title='Feedback' />
  });
