Gotta disagree here - I've seen BMW literature which states the roundel is based on the idea of a prop wash, inasmuch as they originally built aircraft. If those are the colors of the Bavarian flag or province it may be a coincidence.
The blue and white colors are from the the Bavarian flag. The factory PR dude even said so when I was getting a factory tour in Regensburg to see my M3 being built. But, before you start the tour they show you a video about the history of BMW. At one point they show plane headon with the prop spinning and slowly superimpose the logo over the spinning prop.
