Threw together another style of the last few days and I like it.
'tanned,' 'dark skin,' and 'very dark skin' should give progressively darker brown women. Dark-skinned women with a male should remain dark-skinned while the male is white unless you tag 'dark-skinned male.'
The last few models I've also trained in goblin girls and shortstacks, because I like them, but I couldn't get good training data for this set so didn't even try this round.

If you make something nice using this, please share it!
