Blue is always a sweet color, if you plan on powdercoating I would powdercoat the hubs, spindles, sproket and chain hub as well, maybe even the food pegs and levers to give it some contrast, if it is your budget I would chrome the a arms and swing arm or go with another color maybe a silver, white would look good to but would be high maintence. Here's a pic of mine below to give you some ideas. Good luck man and have fun with the build.
