In the volume 1 DVD directors commentary, the guys said that their design choice for Grimm is black, white, red, and sometimes a little yellow (Death Stalker's stinger). So I'm guessing all Grimm are black, white, and red, with maybe a little yellow.

I've figured that her loneliness was sparked by the SDC's conflict with the White Fang. Ever since she was young, she's watched family friends disappear and board members get executed. It's possible that she was kept locked up in the castle for her own safety. If the White Fang captured her, it'd make for great leverage.

That, and it seems like, after losing so many people, she emotionally closed herself up and stopped allowing herself to get close enough to anyone to care about them. That's why she was so cold and mean to everyone in the beginning. It also explains these lyrics from Mirror Mirror: "Fear of what's inside me. Tell me, can a heart be turned to stone?" Even when surrounded by people, she felt lonely because she wouldn't let herself develop bonds with anyone, for fear they would just be taken away like her family's friends.

Though, now that you mention it... she really hasn't said anything about her mother. It'd be especially tragic if her mother was killed by the White Fang.

I've also seen a theory that Weiss received her scar during an attack by the White Fang.
