PushViewController & set navigation bar color and title

Question

I made a push function in a button:

@IBAction func prodButton(sender: AnyObject) {

    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    var secondViewController = CollectionViewController()

    secondViewController = storyboard.instantiateViewControllerWithIdentifier("CollectionViewController") as! CollectionViewController

    self.navigationController?.pushViewController(secondViewController, animated: true)
}

This button pushes to the secondViewController but when I looked at the navigation bar of the second view controller I noticed that it has set up a back button automatically. The problem is that this back button's color is light blue and it doesn't fit with my design. I tried to change it like that in viewDidAppear

self.navigationItem.leftBarButtonItem?.tintColor = UIColor.redColor()

and also the bar color:

self.navigationController?.navigationBar.barTintColor = UIColor(red: 65, green: 61, blue: 116, alpha: 1.0)

but there wasn't any change.

I'd be really thankful if somebody help me with that.

Thanks in advance.

Try to set your color one time, it will be the same color for everywhere after:

let navBar = UINavigationBar.appearance()
navBar.tintColor = UIColor.redColor()

You should put this code in AppDelegate. You could also set the barTint in Storyboard if you use it.
