Color of disc affecting flight?

There has always been much talk of this, I've seen it for ten years. Does anyone have proof of it being true or false? Does anyone know about it from manufacturing-experience?
It seems more likely factors such as temp., humidity, storage, sunlight exposure, etc affect the discs.

I also heard that white was usually the most stable, especially back in the older DX only plastic days. I'm not so sure anymore with the newer Star or Champ plastics.

There used to be a great deal of belief in colors affecting stability back when Cyclones were hot. Blue and green Cyclones broke in the fastest and were less stable, white was the most stable and stayed that way longer. At least it seemed that way to us back then. Can't say there was any empirical proof that would confirm our impression.
