MAC Hautecore is a moderately cool-toned, very dark black with a matte finish. It is a limited edition lipstick that retails for $20.00 and contains 0.1 oz.
MAC Hautecore Lipstick ($15.00 for 0.10 oz.) is described as a "true matte black [with a Matte finish]." It's a deep, dark black with cool undertones and a mostly matte finish. The consistency was creamier than the usual MAC Matte finish, so it didn't tug or drag on the lips, though the color didn't deposit evenly. It does take some finesse and maneuvering to get the color to be as crisp as one might desire. I haven't tried too many full-on black lipsticks, and the only one I could think that would compare was Make Up For Ever #50 (P, $19.00), which is less matte. See comparison swatches. A few readers in the comments (here and on social media) have suggested Illamasqua Pristine as a potential less-fussy black lipstick to work with.
