Purples, magentas, burgundies definitely would make your green eyes "POP", maybe not make them bigger. The way I think about it, other colours make your eye colour pop, while placement of eyeliner makes your eyes look bigger.
I like to line the outer 2/3 of the upper lashline with a black eyeliner and smudge it out with a sponge, then line the outer 1/4-1/3 of the lower lashline and smudge that out too. In combination with a deep purple liner, your eyes will pop AND look bigger. Woohoo!
