everything is polished!
with black forks bars and cranks
i wouldn't do trans red, blue, purple or green, then.
aslo, i'm not too much of a fan of painted forks and bars on a silver/chrome frame.
i would either strip and polish the forks and bars as well (would then look very similar to Tom's bike.) or keep the black forks and bars and paint the frame trans black/gray.
it's up to you, of course.
whenever i can't make up my mind about a color theme, i usually browse bmxmuseum for a bit.
