When looking at these shades I really get confused to what Missha is doing. The shade 25 and 27 is almost the same and way too orangey. The shades might be a perfect match if you are more olived toned. I have always looked for a yellow toned version of Missha's BB cream and before I mixed 23 with 25,27 or 31 to get it more yellow toned. Then I decided to switch to 21 and mix with a darker shades but still no perfect match.
If you are like me, just waiting for that perfect match in shades when it comes to Missha perfect cover BB cream. Just face it will...
