Can you ever have too much piping?

I am a big fan of contrast piping on 1950s cars. I happen to think this looks fanatastic. But is there a point at which it starts to look like a birthday cake?? This blue over blue example strikes me as the perfect balance. But would we feel that way if it was red with white?PS sorry for the radio silence! I was away in Italy. I have some great new photosets in the works!
