The colour of Mr Freeman's Hair

Me and a friend have currently got a lttle arugemnt going on. You see he thinks that Gordon Freeman from the Half Life Games (if you didn't already know...) has ginger hair in the first game. However, I think it is brown. Because it clearly is. To help you guess here isn a useful picture.

I know it's very petty, but I'd like to end this arguement.

Thanks

I think his hair colour has changed slightly. In that picture above, it's clearly brown. But on the cover of The Orange Box, there's a slight hint of ginger, making it look like a dark hazel - it's only apparent in his beard, the hair on his head looks wet or gelled, making it look darker.

Me think its brown.
