Hi im new here too. It's an awesome website!
I am light olive complected also and the green colors that always compliment my skin (and I get compliments on) hehehe, are Juxt, Velvet Moss, and Humid. Hope that helps
I'm an NC30, medium olive, and MAC's Sumptious Olive is my favorite green of ALL time. If you can still find any of the Overrich pigments, Vintage Gold is like a prettier version of sumptious olive... Both are this amazing gold-green and SO flattering.
