I separate my flesh colors into 2 groups:
1) Pinkish flesh colors. -for people who sunburn easily
2) Yellowish flesh colors. - for people who tan easily
Ren is basically a naked Mediterranean man. he always has a slight tan.
I start with an orangey brown color for shaded areas.
Then I use "buff" to do his lighter areas.
I do his main color fill with "Light Sand".
