Some illustrations...

Top left is the original Antonia 1.3 material, top right the new one with a constant base color and no texture maps. Bottom left is the new material with the standard Toni texture by SaintFox and the late and great Digital-Lion, bottom right a variation with the melanin variations a.k.a. freckles dialed up, which one can do by making the spot color in the Freckles node darker.

Please don't pay attention to the eyes and lip/eye makeup. I simply couldn't be bothered to equalize it for all the materials.
