If you really want to make the color of your eyes pop, choose a contrasting color in a soft tone and apply to the lids.
-BLUE eyes come alive with pale peach or soft blues
-GREEN eyes hypnotize with light bronze or caramel tones
-HAZEL eyes become more enticing with chestnut & golden brown shades
-BROWN eyes are nicely accented by almost all neutral tones
-Light Colors- highlight, bring a feature forward or emphasize shallow areas
-Dark Colors- recede or minimize fuller, more prominent areas
Also, apply small amounts of eye shadow at a time because it is easier to add more then remove.
