Nah, seriously, the leather couch sounds good (I've seen, but never owned, some nice ones, very comfortable and chic) but I refuse to own anything white. Even if you can manage to avoid staining it, the moment it gets even a little dirt in one small spot it's unmistakable and you have to clean it. Black or blue leather is just as comfortable and nice but less likely to induce nightmares about chocolate and/or red wine. I don't see how black and white would clash, but if you've already got black anyway continuing with black, or at least dark, colors seems more logical.

Oh, and, yes, I posted; seems that's going to happen every now and then for a little bit yet (but don't get used to it. ) *hugs*
