pupil
do you see with the brown part of your eye if you are
brown-eyed? or is it only with the black pupil?

Neither. The black pupil is a hole in the brown part, which is called the iris. The iris is a ring of tissue which has muscles attached and can contract or expand to let more light through the pupil and into the eye. The lens focuses the light on your retina, which is where the light and patterns are sensed. The sensory information is transmitted to the brain through the optic nerve. You see with your retina, mainly, and with your brain (because it must interpret everything you see).
Hope I have answered your question.
