Apple Documentation for barTintColor says :

This color is made translucent by default unless you set the
translucent property to NO.

Sample Code :

self.navigationController.navigationBar.barTintColor = [UIColor blackColor];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
[self.navigationController.navigationBar 
 setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];
self.navigationController.navigationBar.translucent = NO;

Unable to change navigation bar color

There are two ways to do this. You can either modify the appearance proxy that you have set up in the AppDelegate for the whole app, or you can modify the individual navigationbar for the particular screen.

When you dismiss the view - you need to reset the barTintColor in the viewWillDisappear.

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)

    // Set to new colour for whole app
    UINavigationBar.appearance().barTintColor = UIColor.blueColor()

    // Or, Set to new colour for just this navigation bar
    self.navigationController?.navigationBar.barTintColor = UIColor.blueColor()
}

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)

    //Revert to old colour, whole app
    UINavigationBar.appearance().barTintColor = UIColor.redColor()

    //Revert to old colour, just this navigation bar
    self.navigationController?.navigationBar.barTintColor = UIColor.redColor()
}
