Also I love that her lightsabre is red. I am so fed up of this notion that Jedi/Sith weapons need to be colour-coded as if the writers think we're too stupid to tell them apart otherwise. I understand red is often associated with anger and aggression, but it has good connotations too, such as courage, vitality etc.
Well, in recent Star Wars stories, there are some villains that wield lightsabers that are not red. I know General Grievous wields light-blue lightsabers and there is another Sith lord that wields a special "blacklight" lightsaber. I forgot his name, though, he was in the Clone Wars cartoon.
