The persons I've dated were:
Blond, Blue-eyed
Brunette, Brown-eyed (Russian ancestry)
Black-haired, Brown-eyed (Vietnamese ancestry)
Black-haired, Dark Brown-eyed (Indian ancestry)
And the other persons I've found most striking have been either Blond, Blue-eyed, and very pale, or Black-haired, Blue-eyed, and very pale. Now that I think about it, I think I've been most attracted to pale natural blonds with blue eyes (my childhood phenotype; I've kept the eyes and winter paleness, only my highlights are still blond), but I voted black-haired, blue-eyed a few moments ago. (As it happens, my ancestry is almost entirely Northern European.)
I don't think I'm terribly more attracted to one broad phenotype to another, though (except precisely average height, apparently), as my dating history would suggest. Certainly, I wouldn't have wished any of them were of a type other than their own.
