Having had a chance to drop back and think a little further:
I still would say that "white is beautiful" has, regretably, long been the standard in the western world. But I doubt that there has ever been a time when the typical male was really blind to the attractiveness of a vibrant non-white woman. My own observation would be that a fraction of deeply racist people are actually unable to see physical beauty in whatever group they detest.
As to "blond and blue eyed": I've heard it said that blue-eyed blond babies were always the first adopted; If there is any real truth to that, it would be about the only instance of the blue-eyed blond standard being significant. As others have noted, that standard has been promulgated at the level of pure cultural fluff, largely by Hollywood. So far as what anyone really thinks, I believe you would search a long time to find three American men who would kick Jennifer Lopez out of bed for not looking scandanavian. :)
