Nonsense, if that were the case we'd heard about it by now. Also, the face tracking algorithms can already operate in far less optimal conditions than the one presented here so in _this_ case it shouldn't be a problem. Forgetting that the algorithm was tuned to a specific color range however seems like an entirely plausible scenario.
