Blue eyes do not shift the fundamental values of the human race

Fine, but now you need to specify what you mean by "fundamental values of the human race." :)

(By the way, I recall that there are studies out there corellating eye color with personality traits. I'm not sure if this affects the example I gave, but surely there are other genes which affect personality traits in subtle ways. And it seems likely that some of those personality traits affect a person's fertility given that a lot of people in the West flat out decide not to reproduce. So it's reasonable to suppose that natural selection, as you have defined it, continues in the present and affects human attributes less superficial than eye color.)
