Dunn Edwards has a shade of purple called Dewberry that we painted ours.
You didn't mention budget, but basically you have to work with what is available to listen to at your local showroom. You might not even get close to what you think you are getting, but if they come FR your room you might end up satisfied.
visit some home audio forums and do plenty of research before you move from HTIB to something more "permanent."
I'm trying to drum up some sort of side income in the audio business (now that I'm "disabled") to give the crappy "home theatre companies" some real competition, instead of just putting speakers and a screen in someone's home and telling them "it's the best!" I do cabinet design and experiment with SPL measurement to see what really makes "room gain" sound the least bit decent, and then go for better results with more reliable and way less-expensive equipment.
