I just saw this on KO's facebook page- new colors! On the top are Calamine and Karen, which we already have. But on the bottom- Ox, a matte purple and Liberty, a matte mint green!
These look amazing.
They also mentioned two more colors to be released- Pool and Concrete (I'm going to assume they're blue and grey).
Looks like the companies really are listening to us.
KO polishes can be purchased directly from the company's website, although I have heard some complaints about the customer service.
