[Roa_Aoife]

It seems clear that originally Cirdan's hair was silver. Perhaps the description of his hair being grey was not so much the loss of color (as the greying that our hair goes through in old age) but the loss of the sheen that made it look silver. The soul of an Elf is a bright burning flame. It stands to reason that as an Elf reaches the third stage of life, that flame dims a little, causes them to lose a little of the shine that follows their description in almost every instance. So Cirdan's hair may have been the same color, but dimmed somehow. Does that make sense?
