Category talk:Light-skinned Sims

Worth it?
I have to ask, is starting categories over skin tones really possible or worth the effort, given the variable skintones in The Sims 3? I mean, what one person may define as light-skinned, someone may define differently. I see the same issue with defining thin vs fat sims too, or skinny vs muscular, etc. Is there a way to define in TS3... am I making an issue of nothing?
