Ok, about the darker skin. There IS a treatment. There's a treatment for everything now. But the skin is darker? Wow, my skin is lighter.
For the others, Europeans aren't all white. My step dad is full itallian and he looks like african mexican. I'm philipino and I'm white. My teacher last year is born and raised and fully African but he's white as hell. So just because you're from a certain place doesn't mean that you need to be a certain skin color.
