Taz, I think you miss the point. Off course it is easy to tell the color of a person. But does that constitute race? For instance, a black person can have african origins, but might also have australian origin. these two groups are not closely related. So we need more then color to define race.
But once we start adding other characteristics things get only more unclear. should we use average height? there are some pretty tall people in nother europe and in sub-sahaara africa too. There some short people in Africa and in Asia too. So, height does not cohoborate the tentative definition for races that was achieved with skin color. You might thinkmay be if we add even more characteristics, things we become clear. But the poin is that they don't. The only honest conclusion seems to be that there's no such thing as true race in the human population
