hi there . im a makup artist and i think dark green suits green eyes it really emphsisis them also brown looks great to for a change . keep away from blues
if you go into boots, one of the make up brands (i think it's almay but i'm not sure) has little cards which show you how to do the best eyeshadow for your eye colour. doubtless it's a personal preference but they look quite cool. from what i can remember they suggest purple on the lid with some green blending to the brow bone. I like purple personally
