Any time I try to match things to something else, like blue with blue, it always winds up looking like I tried to match it. I find that when I contrast, it is so much better! I'd let the blue stay on your bike and make the blue accents be very small items. I like the thought of white for saddle and tape, or keeping it black. I'm afraid that if you get blue tires, blue bar tape and blue seat, you are going to have a dozen different shades of blue that don't quite match. I kind of like it like it is in the picture! Sort of a ring of black around the blue middle!
