ColourPop Mr. Blonde Ultra Matte Liquid Lipstick ($6.00 for 0.11 fl. oz.) is described as a "bright true turquoise." It's a brightened, medium sky blue with cool undertones and a satin-matte finish. It was mostly matte, but there was an almost vinyl-like sheen to it--and it took forever to dry down. Even when "dry" after a half hour, there was still a very light tack in places. This shade had intense pigmentation that went on smoothly and evenly, but it had a thicker consistency that "cracked" as soon as I smiled. It felt a bit clingier, and it was prone to flaking from the center of the mouth over time, though the majority of the color was intact after six hours. The formula was somewhat drying overall.
