Yesterday on my lunch break I was sitting at a picnic table in the shade on a sunny day when I noticed that my nail polish, Zoya FeiFei, had RAINBOWS all over it. I was freaking out, thinking, "this polish is actually holographic! Zoya's never done that before! HOLY CRAP, I better take some pictures or no one is going to believe this!" So I did, with my iPhone:
So I looked around... nothing... then up... and realized I was sitting under a rainbow umbrella much like this one.
So, no, FeiFei is not holographic. It's still beautiful, though! :)
