It's simple genetics. My sister has red hair and a majority of our birth family (including me) has brown hair. To be fair, though, we're half-sisters through a shared mother but I think one of our mother's brothers was also a redhead like my sis's alleged father. So the resessive gene for red hair showed up in my sister while I got the dominate brown color gene. That's how it works.

Chances are there was a Pie ancestor who was pink and it recently just reappeared with Pinkie. Also, Pinkie's mother is grey, not brown.
