Why does my eye have 2 different colors around the pupil, if you look up close?

Natural variation. Assuming that there is nothing wrong with the eye (vision ok, no trauma, no redness, no pain) then what you are probably seeing is the natural variation of the iris color which can be patterned, variegated or as in your case sort of an outer ring of a different color than the inner ring. Enjoy the beauty of this as it is not harmful and will not affect eye health.
