MAC Nude Lipstick ($16.50 for 0.10 oz.) is described as a “cool nude cream [with a Matte finish].” It’s a medium-dark brown with a gray cast–almost slightly rosy-toned at certain angles–and a matte finish. It had opaque color coverage, and it felt very creamy, even for a matte (which is different than a Retro Matte!).
MAC Shitaki is warmer, shimmery. MAC Double Shot is warmer, richer. Guerlain Giny is much lighter. Bobbi Brown Uber Nude is rosier. See comparison swatches. I think MAC’s permanent range may have some similar shades to this, but I’m not familiar enough with some of the browner shades to say for sure, though.
