According to Linda's SimDNA in SimPE, her hair was red before it turned grey. According to her age data, she had 14 days left in the elder life stage when she died. Linda uses the 9th Maxis face template in Create a Sim, except the mouth which uses the 8th face template. Also the lower face width is slightly narrower than on the default, though it is only narrower on teenage, adult, and elder male Sims, which may mean that the face was genetically passed down, as this oddity generally only occurs on Sims whose facial features were genetically passed down.
