As far as I'm concerned, blue is for bikes. I've got a blue reflector (among others) or blue reflector tape on almost all of my bikes. White - Yellow/Amber - Red - Blue from most to least reflective.
But I keep the reflectors and lights limited to my bike and bag, and generally wear street clothes to ride, often black. Bike clothes are for bike dorks.
