It depends on your eye colour, for example let's say you have blue eyes, you should probably wear a bronze or silver eyeshadow. Now let's say you have brown/black eyes, try a shimmery gold. If you have true green eyes, then you could pull off a violet or try a metallic. And finally if you have hazel eyes you could do either the colour for brown eyes or green eyes.
Of course if your too lazy to deal with all that colour matching you could do a nice light pink or beige.
