Snowskin is insanely white like paper or fabric, Dollzone beauty white is a slightly yellower tone than Obitsu white. My oldest DZ is almost a shade darker than my white Obitsu 60.
Some of the best ethnic 1/6 guys I've seen, in a rich shade of brown with realistic head sculpts, have been the Power Team Elite. Mattel is doing something with the SIS line that come somewhat jointed. and in several shades. I had several Shani dolls for a few years, didn't play with them much, then found a new mommy for them who was beside herself to have a doll that matched her. It may just take more things like the Princess and the Frog to change people, and at least that way they're starting from the ground up.
