Well...to each his own, but since you asked, I'm of the camp that prefers a shaded or dark facing surface on the front sight especially for match/paper shooting. Mine is tapered toward the muzzle with the highest point toward the rear sight. A good square post, about .1"thick is fine with a 36" or longer barrel. If the barrel is shorter...may need a little thinner sight. I also sometimes add a little blackening with a match or candle (on an iron sight) or in a pinch magic marker to make sure there are no bright edges to reflect light. That being said, I'm sure the ligic with a brass front sight is to have a glint of sunlight to show up against a daker (deep woods) background while hunting. You see it on a lot of original rifles. I'm just saying I prefer a black post for most range shooting and the hunting I do.
