Changing the colour of UIPageControl dots in MonoTouch

Question

I was wondering if MonoTouch allows the developer to change the colour of UIPageControl dots to suit a light background - they seem to be fixed white, which makes them very hard to see on a light textured background.

I am aware there is no public API available for this but I was wondering if anything was internally implemented in MonoTouch to improve on this.

Otherwise, what's the recommended approach to using a UIPageControl on a light background?

I took a stab at translating this. I'm not sure it will work, but it does compile. Note that the page linked to contains comments indicating that Apple frowns upon this code and may reject it:

using System;
using MonoTouch.Foundation;
using MonoTouch.UIKit;

namespace Whatever
{
    public class StyledPageControl : UIPageControl
    {
        public StyledPageControl () : base()
        {
        }

        public override int CurrentPage {
            get {
                return base.CurrentPage;
            }
            set {
                base.CurrentPage = value;
                string imgActive = NSBundle.MainBundle.PathForResource("activeImage", "png");
                string imgInactive = NSBundle.MainBundle.PathForResource("inactiveImage", "png");
                for (int subviewIndex = 0; subviewIndex < this.Subviews.Length; subviewIndex++)
                {
                    UIImageView subview = this.Subviews[subviewIndex] as UIImageView;
                    if (subviewIndex == value) 
                        subview.Image = UIImage.FromFile(imgActive);
                    else
                        subview.Image = UIImage.FromFile(imgInactive);
                }
            }
        }

        public override int Pages {
            get {
                return base.Pages;
            }
            set {
                base.Pages = value;
                string img = NSBundle.MainBundle.PathForResource("inactiveImage", "png");
                for (int subviewIndex = 0; subviewIndex < this.Subviews.Length; subviewIndex++)
                {
                    UIImageView subview = this.Subviews[subviewIndex] as UIImageView;
                        subview.Image = UIImage.FromFile(img);
                }
            }
        }
    }
}
