First things first I'm gonna show you photos of people with the wrong eye shadow color if they were trying to bring out their eye color it would not look right.
This color does not suit her beautifull Blue eyes she has blue over blue WRONG!!!!!!
Shocking but Katy perry has the wrong eye shadow on if she was trying to bring out her green eyes it would not have worked purple over hansel or green BIG NONO
These colors are beautifull but they do not suit the women's eye color
This is a yes and no if your eyes are dark brown you don't putt brown on your eyelids but if your eyes are light brown then yes
These are the colors of our eyes
These are the colors you can use
Grey eyes = purple eye shadow
Blue eyes= gold eye shadow
Green eyes= brown eye shadow
Light brown eyes= white eye shadow
Dark brown eyes=orange+white
