I prefer satin anodized or polished metal that's not colored myself. Chrome lugs and dropouts are sweet too. When it comes to the frame I like a gloss finish. I do have black calipers, headset and rims (original) on my Trek 460 and they look good against the lipstick red frame.
I can put up with most colors - my first serious road bike was only available in the color I didn't want but it's still a joyful ride a few decades later.
