Eastern Europe is very diverse due to centuries of different admixtures and migrations. Common Polish looks (if you are interested in anthropology) are most commonly Gorid or Baltid types, but there are many mixed versions of these types or others there.
I was born in the United States and have never visited Poland, however, my Polish family including my mother are almost entirely blond haired and blue or grey eyed. I have dark blond hair and light brown mixed/hazel eyes.
