I have anthracite (that's it in my avatar picture) and it is a good color for every day, if that's what you're asking. It's dark enough not to show a lot of wear or dirt, and the color is very versatile.
It was only out for one season, as others have said, but wasn't limited edition like magenta (where they only made 500 or so.) Depending on the style and hardware you want, it will be hard to find new at this point. I made probably 15-20 calls to stores back in early July to find my RH anthracity, and there were only a few GHs left then too. You may need to check eBay and reputable consignment stores to track one down.
