Ah. Okay.

blue3 was proposed specifically for light-background themes.

Yes, that's my impression. Text goes from dark-on-white to light-on-white.

Yup.

Yup.

It is indeed subjective. I'd like to just reiterate my impression: that 
blue3 distinguishes itself from the black text _too much_.

blue4, on the other hand, somewhat blends in, but in doing so it avoids 
the problem of being too in-your-face with prefix completion. And lets 
the users know anyway that if they really want to see the common part 
more prominently, there is a face they can customize.
