I thought the common theory was that Athena only really fell in love with blond men? (Regardless, though, the fact about all of her kids having blond hair was mentioned all of once in canon, and then later disregarded, just like many things. Because Riordan cannot keep his frickin' canon straight. T_T So I've always, personally, assumed she had kids with other hair colors. *shot*)
