This thread is a lot of fun to read!
In one of my very first Sims 1 neighborhoods, I named each of the several families after a color (Brown, Violet, White, etc.). My favorite sim was one I named Celine Green--a skinny, pink-haired, musician type (in other words--nothing like myself, lol). She was so much fun to play that I've replicated her in every Sims version since, and named my forum self after her, too.
