I got this for my mom, color 23. She's got a yellow overtone, but is pale and has a cool undertone. She really liked this. She said it didn't empahsize texture. I ended up getting her this, the Missha BB Cream, and the AGE20 essence cushion. Her favorite was the AGE20 cushion LOL. This was the same woman who refused to wear foundation because it "always looks cakey"
But yeah, this is a perfect shade match if you have a yellow overtone but are cool toned. And pale.
