How would the world react to someone like this?

I had a interesting thought cross my head today and I am just having to ask it here and hopefully its okay..

So I'm wondering being the world is so cruel and there is so many racist people out there.. How would the world with people like that react if there was a man or a woman who was born both skin colours? Like both in the sense that half of their face is white the other half is black and they are just naturally that way?

I feel like with how human body works that something like that could be possible even though there is no record of it ever happening to date.
