It's possible they did (anything is POSSIBLE....), but no record exists of this practice in the Icelandic sagas, which are our best source on Norse custom of the time.
More time is spent describing the clothes of the participants, which is in itself, a means of communicating mood and intentions to an opponent; in Njal's Saga, for instance, Skarp-Hedin dresses in an ostentatious fashion before going into a fight, the intention being to advertise his presence to his enemies. Mention is also made of a red 'war shield', a shield painted wholly red to declare an intention to attack without the chance to parley.
If you're a re-enactor, steer clear of war paint, or you'll look like one of those idiots in that useless film, 'The 13th Warrior'.
It should be pointed out here that the Viking Age began long after the fall of the Western Roman Empire. Saying the Romans were afraid of them is absurd; it's like saying that Elizabethan England feared the Taliban, when there were almost 400 years between them.
Long-term interest in history, especially the Viking Age, 12 years as a re-enactor.
