i agree w/ mythology being underrated!!!!! so mythology, swish, jest, naked lunch, steamy, coquette, seedy pearl, mulch, trax, au contraire, juxt, ....
My faves are Freshwater for vibrancy, Femme Noir for lining/smoky eye, Mink Pink as a base but also to make the eye area skintone look even and flawless (or close!). I also love Beautiful Iris as a wash.
Vanilla, Retrospeck, Phloof! (for highlighting the browbone and the inner corners of the eyes), Woodwinked, Pink Papillion, Petalescent... etc. (i go for naturals/pinks)
Asking us which eye shadow colours are the best is like asking kids what candy is the best... Everyone has their favourites - and the list of favourites can get pretty long.
I've actually been told that I probably collect eyeshadows because they look like candy.
