I think, technically, you're supposed to take a light color and a dark color and do some mixing. I'm a little lazy and for some reason I have a lot of pinks in my collection (surprise, surprise) so I did it the easy way.
I took the pics with my phone, so excuse the badness. My rechargeable camera batteries aren't holding a charge anymore and as I've mentioned before, I'm a little lazy so I haven't gotten around to buying any yet.
China Glaze White On White
OPI Bubble Bath (my fave)
OPI Pink-ing Of You
NYC (not only can I not find a name on it, I also can't even tell you how old this polish is!)
