How to make my eyes pop?

I have a lot of freckles with olive green eyes that to me can sometimes seem kinda flat, what are some good ways to really make my eyes pop w/o going overboard w/ the makup.. im 15 and I basicly like a natural look -very little foundation- and usually I just use some mascara.. any tips?
P.S. I have really white skin so that makes foundation a problem cause it makes my freckles look weird.

put on brown eyeliner. that will make them stand out a little more without looking unatural.
I would also find a good eyeshadow that matches your eyes. go to a good makeup store and ask the people there's opinions, theyre really good at that.

First of all... try some different colours of eyeshadows, like purples, greens, browns.
Also... if you go on youtube.com you can watch videos that have a lot of awesome make-up techniques.

Sounds like I have the same colouring as you. Purple will make them pop, but for an understated, more natual look, peaches also contrast and will make them stand out too. And just try using the lightest shade of foundation. If that's too dark, mix it with moisturiser to dilute it.
Green eyes rule.

use yellow eyeshadow or a BRIGHT blue.

using a dark blue eye liner will make the white of your eyes look whiter which will make your eyes seem greener. if you want the greens to come out use plum shades and pink shades. gold shades are also good. I have hazel eyes and I use more earthy tones that make my eyes pop. too much makeup will make you eyes seem to go away or look smaller. a little goes a long way, I like the natural look too. so some light browns would look good. use some bronzer and a dark brown mascara only on the top.

wear light lilac eyeshadow witha green tited mascara
