Human beings have likely always been able to see the color blue since we broke off as a species from the other primates and other primates can also see blue. Thus, the evolution of the cones to see the color blue probably occurred before humans existed.
Interestingly enough, some humans appear to be quadrachromats or quadrachromatic. At least that is what I heard in an image processing course.

Is this a homework question or a serious question? Going the scientific route, which I guess is what you're looking for, there's really no way to know. How could we possibly test fossils for the presense or absense of cones in the eyes?

We didn't 'acquire' it, we were created with it..
