Kapow

ColourPop Kapow Ultra Matte Liquid Lipstick ($6.00 for 0.11 fl. oz.) is described as a "muted greey taupe." It's a medium-dark, purpled taupe with neutral-to-cool undertones and a matte finish. This was less of a flat matte finish and more of your traditional matte finish, and this shade had a much longer drying time compared to a lot of the range, so you'll need to be careful as it dries down to avoid pressing your lips together or else the color will lift/flake off where the lips meet. I had very slight "cracking" with this shade after an hour and a half of wear. It was fairly comfortable to wear until four hours, where it felt a bit drying,a nd it lasted for seven hours.
