Determination of Ascorbic Acid using colorimetry

I'm working on my chemistry investigation, the determination of ascorbic acid, and I have found a few titration methods so far. I was hoping to find another method which was different, and colorimetry was one I was told about that could be useful. Unfortunately I have not found any suitable or reliable methods to use! I've already done a lot of background to it, what colorimetry is etc.
Apparently there's one using Iodine solution?

If you could suggest a reasonable method for the determination of vitamin c/ascorbic acid using colorimetry that'd be great :smile:

This isn't a joke, I've googled this thing dozens of times, I just wanted to find a simple and easy one, involving iodine. All of the methods that I've found are far too complex and you have to pay to read most of the articles. I asked for genuine help, not some sarcastic response.
