According to Martha's SimDNA in SimPE, her hair was black before it turned grey. According to her age data, she had 19 days left in the elder life stage when she died. Martha uses the 4th Maxis face template in Create a Sim, except the eyebrows which use the 10th face template, and the ears and mouth which use the 8th face template. 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.
