Well, I guess that not all Twilight 뱀파이어 have to be pale from...well, what 당신 just said; Laurent is black. Perhaps whether a vampire becomes pale 또는 not depends on his/her ethnicity. If a vampire was Caucasian 또는 Asian, any ethnic background that allows them to have white skin, then maybe they are the ones who are shockingly pale. However, if a vampire was African-American 또는 Hispanic 또는 any other ethnicity that makes the person have a dark skin color, they keep the skin color they had when they were human. So maybe this explains why Laurent, unlike most vampires, is so dark skinned.
And don't worry, it doesn't sound racist at all! That's actually a pretty good 질문 to me :)
