Cumulus is described as a “dirty grey charcoal [with a Frost finish].” It’s a subtly cool-toned, dark taupe with an olive-brown base. It had nice pigmentation, and the texture was really soft and buttery. MAC A Glimmer of Gold #4 (P, $21.00) is less frosted. MAC Silver Dawn (LE, $19.50) is warmer. Urban Decay Vaporize (LE, $18.00) is more glittery. MAC Shale (P, $15.00) is browner. See comparison swatches.
