It has a mostly matte, black base and then it has that dark green-teal shimmer/frost. Urban Decay Loaded is similar but not as black. bareMinerals Max Volume is a bit lighter and less black-based. OCC Poison is greener and lighter.

Carbon is part of the permanent range, as well as come out in various palettes over the years, so you may find you have it at least once in your collection already.
