I guess that depends on what the model is used for. If you like a model that looks realistic but has no texture, then go for your favorite skin tone.

If you like something that is not to “scary”, then get something more playful and make it rainbow-colored, thermochromic or better: glow in the dark. There is a reason why most sex toys (for women) are not flesh colored.

If you want to create an educational model for adults, textured would be nice.

Try the same colored model for sex ed in school and you will have very interesting conversations with concerned parents. In that case, you might also be better off with a color gradient or an unusual color (orange, green, blue, UV active).

And that way, you elegantly avoid traps that involve racial stereotypes.

Try it on wearebeautiful.info, the render engine allows you to change the color of any model you pick.
