Black vs. White eyeliner

Hey Everyone,
Something that I've been really into lately is defining my lower water line with a nude eye liner.  While applying my eye liner the other day I started thinking about the phases I've gone through with eye liner.  From rimming it corner to corner with rich black pencils, to adding a little pop of color, and now my latest phase in lining, white or nude liner.  Something I've noticed over the years is how black and white eye liner leave such different effects on your eyes, and today I thought i'd compare the two styles of lining for you.
