ColourPop Knotty is a moderately warm-toned, medium peach with a matte finish. It is a limited edition lipstick that retails for $6.50 and contains 0.11 oz.
ColourPop Knotty Ultra Matte Liquid Lipstick ($6.00 for 0.11 fl. oz.) is a deep peach with warm undertones and a flat, matte finish. It was incredibly rich in pigment, but the drydown was terrible; it was thin to the point where it looked "cracked" when I smiled, emphasized every line on my lips, and just looked like my lips lacked moisture. I'm not sure why some of ColourPop's Ultra Mattes dry down like this--almost chalk-like, clingy, and ver dry--while others have a smooth, matte finish that while drying after hours of wear doesn't look shriveled from the get-go. It lasted for five hours but had flaked away unevenly from the center of the mouth after two and a a half hours.
