Blond isn't just a word used to describe pale yellow hair, it can also be used to describe a person with such hair. We'll leave it to you to decide whether or not blonds have more fun.
There's all kinds of blonds out there from bleached to platinum to strawberry to sandy. Some people, Brits especially, will add an e to the end of blonde depending on what gender they are talking about, so that a woman is blonde while a man is blond. The addition of the "e" in the feminine form of blonde is of course a holdover from its French origin. Not only fair-haired people are described as blond; you might have seen blond wood used in Scandinavian furniture. Ikea, anyone?
