Чего вдруг у него черные? У него нормальные серебряные. Как мне помнится, и Вики говорит.
Нашла цитату из "Пира ворон", где Серсея думает, как Ауране Уотерс похож на Рейегара, в частности своими серебряными волосами:
The other cousin, Elinor, was sharing a cup of wine with the handsome young Bastard of Driftmark, Aurane Waters. It was not the first time the queen had made note of Waters, a lean young man with grey-green eyes and long silver-gold hair. The first time she had seen him, for half a heartbeat she had almost thought Rhaegar Targaryen had returned from the ashes. It is his hair, she told herself. He is not half as comely as Rhaegar was. His face is too narrow, and he has that cleft in his chin. The Velaryons came from old Valyrian stock, however, and some had the same silver hair as the dragonkings of old.
