I couldn't reply in time before you made your edit, but truthfully I was going to post the same thing: I was struggling with how to phrase my original comment, but I was looking for a shorthand way of saying "people with light pink and white skin" without coming off as either callous or overly euphemistic. Really, my curiosity stems from being new to how neural networks work -- naively, I've grown accustomed to processes where the outputs reflect the input, and at first blush to me, supposing a varied dataset, this didn't appear to be the case. Those who replied to me provided persuasive arguments as to why the hues of the synthesized images may not necessarily imply that the training dataset wasn't that varied after all.
