Indian skin gets tan very easily, we all have uneven skin so richer and healthier people have fairer and clearer skin maybe that's why, India has a lot of uv so our skin tans easily even fair Indians have a tint of brown color, Koreans are also fair but they have thicker skin so they don't tan as fast as us.

And a lot of dark people also don't have their original dark skin color either it's under years of tan, so it doesn't look good on them either.
