Do comments turn gray after a single downvote? I honestly don't know. I personally don't care much about whether comments are gray unless they've turned the "I can barely read this" gray. The standard (first level?) gray just tells me that someone (or a couple of people) downvoted the comment, but that doesn't mean much. I've often "rescued" gray comments. The ultra-light gray often does indicate something and I'm less likely to read those.
