Honestly Olivia doesn't even have negroid features, that's why in
>>29130912 despite the shit coloring job her features still look within reason for a fair-skinned person.
You can color an anime girl brown but she'll still have cartoonish anime girl features that aren't horrible like actual negroid features. Negroids have nasty hair, wide noses, an ugly head shape, and huge lips.
Pic related, this is a character with negroid features and recoloring her as lighter wouldn't save anything.
