Some years ago I had an all-black Strat: the entire neck/headstock was black, the body was black, it had a black pickguard and all black hardware except for a few pieces (whammy arm, screws) that were chrome. It was a pretty axe, but not really what I wanted.
My other guitars have had nickle, chrome or gold, until I bought a Carvin SH550 last week with a cedar top, antique yellow stain top, and a Bigsby, with black knobs, tuners and pickups. I don't think it looks bad, although, had the Bigsby been black, I might have objected.
Any color that's integrated into the look of the instrument is good, in my opinion.
Here is a guitar we make for a different company. I ended up making one for myself and ended up trading Gary @ Glaswerks for his Zingaro model (great amp) for this guitar. Dave Manicetti from Y&T plays one of these.
