Science doesn't talk about "purpose". Science is about How not Why.
What is the scientific purpose of humans having genetic variation with different eye and hair color?
You will find that certain genetic variations generally originated from specific areas. e.g. blonde hair and blue eyes originated in northern Europe, Red hair and green eyes originated in Scotland and Ireland, etc. The most common hair type is dark, that is brown and black, and the most common eye type is brown. There are many possible reasons for this from camouflage to survival of the elements, to the basic principals of attraction and reproduction.
