I ended up getting NC40 for this foundation. I was originally matched at NW30 (eehhh). The SA said my face had pink undertones therefore the NW. But my body is yellow with NO pink undertones. It was a free sample so I tried it out anyways so I could atleast get the feel for the formula. LOVED the formula. Dried fast, no need for a setting powder, kept me from being oily (a blessing since my skin is oil hell), gives amazingly natural finish, lasts 12+ hours. So I decided to try for another color. Went to a new SA and she was surprised I got matched with NW30. So she switched me to NC40. PERFECT match. Now my face matches my body haha.
