According to Melanie's SimDNA in SimPE, her hair was blonde before it turned grey. According to her age data, she had 18 days left in the elder life stage when she died. If Melanie is resurrected and aged down to an adult, it becomes clear that she uses the 25th Maxis face template in Create a Sim, which is one of the two broken face templates; except that her eyebrows use the 27th face template, which isn't broken. Also the jaw is longer than on the default face. However the jaw is only longer on teenage, adult and elder females, which may mean that the jaw was genetically passed down, as this oddity generally only occurs on Sims whose facial features were genetically passed down.
