Mars is described as a “bright metallic green shimmer.” It’s a medium-dark, cool-toned green with bluish undertones and an emerald green micro-shimmer. It had pretty good color payoff in one pass, and it was definitely buildable to rich, opaque color in two layers. It wore well for eight and a half hours, and after nine and a half hours, I noticed it was thinner but had not smudged or migrated. This shade is new and exclusive to the set. Sephora Good Mood is darker, greener. Make Up For Ever #52L is very similar. MAC Blue Noon is less shimmery. Urban Decay Covet is slightly darker, less green, but similar. MAC Minted is darker.
