I agree with GB who posted in another thread that it's that way by design to differentiate the two sights and draw your eye to the front.
My front sight is like a headlight out there in the dark but the rear sight is plenty visible.
I have a set on a nightstand and I can find my way to it in total darkness just watching the sights.
