Blondes or Brunettes or doesn't matter?

This is actually just something my boyfriend and I are “arguing” about. He thinks guys mostly go for blondes and girls mostly go for brunettes. I personally disagree and assume it is pretty even for both genders, (It actually happens to be brunettes for me, but I’m sure many girls would say blonde!) I’m trying to take a survey to see who is right! By saying one or the other doesn’t mean that you would never be interested in a girl or guy without that hair color, it is just saying that girls or guys with that hair color are who you are immediately attracted to. So if you would, could you please tell me your gender and your preference?
