Faramir with dark hair?

[Duncariel]

O.K. I was reading ROTK for like the sixth time this morning and noticed something new. In chapter 5 of book 6 it says

And so they stood on the walls of the City of Gondor, and a great wind rose and blew, and their hair, raven and golden, streamed out mingling in the air.

Since Eowyn's hair is obviously golden throughout the book, and ravens are black, does this mean Faramir's hair is black? Dumb question.
