The Latin and Greek speaking parts of the world probably had a word for purple by that point. Remember the Angles, Saxons, and Jutes who would evolve into the medieval Anglo-Saxons were from around modern continental Denmark to about the modern Hanover region. This area didn’t really have the color purple all that much and frankly speaking Britain ain’t much better on that front, probably why it took till around the viking age to get a word for it since that’s when pan European trade started to pick up again to a large enough degree for purple dyes to start getting to Britain on a regular basis.
