I highly recommend this if you are looking for a new foundation. It was very easy to test what color works best. I always buy the wrong color, this solved that problem.

I loved being able to compare different shades. In the end I unfortunately did not find a better match than my current foundation. I found Kosas to be a touch too yellow, even the neutral or cool. The coverage of the foundation is gorgeous and I was sorry not to find a shade that worked for me. I'll try again if Kosas ever adds different shades. I did end up finding a shade of revealer concealer that works fantastic.
