Jeff said "Others may see it differently, but I would call the two below "Viceroy" and "Siffert" color schemes" (my emphasis). Not that he would call the watches a Viceroy or Siffert. Looks to me like you're both in agreement in fact :) One of those problems caused by the Autavia's suffix relating to the bezel rather than the dial colour, it's not something that causes much of an issue in Carrera world. Nor is there the drive to name models after wearers either, though we do occasionally have to concoct a name to make a distinction - "yachting" 1153 anyone?
