ColourPop More Better Ultra Matte Liquid Lipstick ($6.00 for 0.11 fl. oz.) is described as a "deep violet wine." It's a dark, berry-red with cool undertones and a matte finish. It had semi-opaque color coverage that dried down quickly but with enough time to apply it. The texture was soft, a little dry in feel to the touch, and it lasted for five hours on me--but it faded unevenly. It was somewhat drying. NARS Blindfold (LE, $27.00) is lighter (95% similar).
