Don't make me sit around imagining what you look like. Heh, I got an idea - let's all make Sims that we think look like other members. This'll be fun.
I'm using a netbook at the moment (like I always do for Carl's forum), and if I adjust the tilting of the screen correctly, the hair seems dark brown. At first glance it did seem black, but it definitely looks brown now. My friend in real life has extremely dark brown hair that looks black most of the time. In good lightning, you can see that it's brown, though.
