I'm assuming you are more of a "cool" tone girl. Does gold or silver look better on you? If it's gold, you would like to stick with "warm" colors like brown, maroon, gold, etc. If you look better with silver on, then you are cool tone. Then if that's the case, you would want to use blue, grey, pale purple, etc to match that tone. Luckily, you have brown eyes. Brown eyes can pull off any eye shadow color so the only think you have to worry now is the skin tone.
