I decided fairly early on that the easiest color for the couch would be the taupe (second in the picture). It's a neutral, which I'd want for a big piece of furniture we'll be keeping for years. I even found this pretty cotton velvet fabric that I liked:

I briefly contemplated going golden yellow for more punch, but right now I'm digging the idea of a black velvet sofa. Not inky, boudoir shiny black velvet, but almost charcoal with a broken-in feeling. This couch is very similar to mine and I love the look. It even makes me want to keep the skirt on my sofa.
