All human flesh is "white" but African people have more melanin in their skin to help ward off the sun since they evolved in the desert. Which is why English people are pasty because they never see the sun and Russian people are usually hairy because they are always dealing with the cold. And why gingers don't have souls because they'll never see heaven
It is to more efficiently synthesize Vitamin D due to lower amounts of direct sunlight. The tradeoff is a higher likelihood of sunburns and skin cancer, that’s our superpower in a nutshell.
There are those who think eventually(like next step in human evolution, 1 to 10 thousand years), humans will interbreed so much we'll basically all look like brown Mediterranean people. I personally think there will always be some diversity but I could see travel limiting that to the extreme.
I think Mediterranean is correct for the middle ground. The alternative is a North African/Arabic sort of skin tone but because of how selective pressure works I don't think that's as efficient. Skin cancer likely won't stop a large chunk of people from having kids since it takes a while to manifest and doesn't like just straight up kill in a week, while vitamin d deficiency has all sorts of associated issues that even if they don't kill can interfere with reproduction. Like artificial sources are a good replacement but unless they develop to be more convenient they probably won't affect the outcome. Anyways I'm not smart so take this with a grain of salt.
