U shud get u're "colors" done from a consultant..he/she will write down what colors would look fab on u! If u have olive skin get urself a good foundation that matches perfectly and blends well. Then get urself an eye-shadow pallete with colors like copper/gold/silver..blue..purple and deep brick.
For lipsticks get a tawny color, pink, gold-brown and a nude one. u prolly will need max 3 lip-pencils!
Foundation, Eye liner, Mascara never be stingy on these products!
