Why are elves rarely portrayed as black?

Usually elves are portrayed as either white, other European, Asian or Middle-eastern in movies, TV-series, games and in other art. I'm curious if it's written a place which human phenotype ("race") an elf are supposed to resemble mostly. E. g. the authors saying: "Elves are tall and have fair hair, eyes and skin" or something like that: "Elves have narrow noses, slim faces and big eyes".

I've noticed a lot of racial diversity among elves, but rarely seen any black elves. I'm just curious. No, I'm not accusing anyone for being racist. I'm just asking if there are any traditional or cultural reasons for it; if there's a meaning behind it or if it symbolizes something special. Same reason I'm curious on why witches are either portrayed as old, ugly and green hags wearing pointy black hats and having a big nose and why more human looking witches are portrayed as either redhead or blackhead. #Elf #Elves #Race #Black

It's not only white elves I've seen. But also East-Asian (Chinese/Korean/Japanese looking), Arabs, Persians, Spaniard, other Europeans etc. It's rarely black though like West-, South- and Central-Africa and Australian aborigines. Beautiful people exists everywhere on earth. Did whites in the past see fewer blacks than other none-whites?
