I have my 2006 520 in sage green. Funny how I won't put too much thought into my own clothing coordination (ask my wife), but I'll put thought into how things look with the bike. I have a dark green Brooks saddle, red handlebar and trunk bags, and red panniers. Since I have small children I don't have the time/money/freedom to tour as much as I'd like, but I use the 520 as my only bike right now -- commuter, club rides, charity/century rides, and now as a towing bike for my son's Novara Afterburner (trail a bike). Here's a shot of the 520 in its latest role. We're training now for the PALM ride across Michigan in June.
I've also added two photos of the 520 fully loaded, from a trip to the Outer Banks of North Carolina in '07.
