My opinion:
Fuckin awesome going black! Do the swinger black, screw blue, do everything black and get black plastics.
Little chrome makes a nice contrast.
If you insist on a second color, go with something other than blue. I've seen Blue/Black combos and they don't compliment each other. IN MY OPINION.
Yellow, red or maybe silver would look a bit better. But all Black is the badass way to go.
