My Henna red LS has the original paint, and original (blue) stickers on it.
The theory held be numerous people is that the stickers were not applied at the factory, but were shipped to the dealers, who applied them. Depending on the dealer's aesthestic preferences, sometimes blue stickers went on red bikes, and sometimes black&white stickers went on silver bikes, though I think that the factory originally planned for the black/white stickers for the red bikes and the blue on the silver bikes.
