What color eye shadow should you wear if you have blue eyes?

Colors that mimick your natural skin colors. It starts with the skin so make your skin look nice. Lip color one or two shades darker than your natural lips. As for eyeshadow, if you have:

Brown eyes: A light sweep or translucent purple looks nice. You can use any color

Blue eyes: Same except browns and purples look the best. Blue with blue is a no-no.
