See my setup method's code in which I change page view controller's page control color and it's worked for me.

private func setupPageController() {

    self.pageController = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil)
    self.pageController?.dataSource = self
    self.pageController?.delegate = self
    self.pageController?.view.backgroundColor = .clear
    self.pageController?.view.frame = CGRect(x: 0,y: 0,width: self.view.frame.width,height: self.view.frame.height)
    self.addChild(self.pageController!)
    self.view.addSubview(self.pageController!.view)

    for item in self.pageController?.view?.subviews ?? []{
        if item is UIPageControl{
            (item as! UIPageControl).pageIndicatorTintColor = #colorLiteral(red: 0.501960814, green: 0.501960814, blue: 0.501960814, alpha: 1)
            (item as! UIPageControl).currentPageIndicatorTintColor = #colorLiteral(red: 1, green: 0.7489039302, blue: 0, alpha: 1)
            break
        }
    }
    let initialVC = strBoard.instantiateViewController(withIdentifier: "TutorialOneVC")

    self.pageController?.setViewControllers([initialVC], direction: .forward, animated: true, completion: nil)

    self.pageController?.didMove(toParent: self)
}
