Clockwise from top left: Ubangi, Tatar, Baalbek and Snake Eyes
All of the NARS eye paints I've tried have staying power comparable to Bobbi Brown's gel liners and MAC Fluidlines.
Baalbek: This one was part of NARS's summer 2014 collection. I thought it looked more olive in the pot but when I swatched it I realized it's more of blackened gold. I love it with bronze or green shadow but it works well with neutral shades as well - I find it really gives a zing to the beigy-gold side of NARS Lost Coast eye shadow duo (also from the summer 2014 collection) or the muted shades of the Vent Glacé duo.
Snake Eyes: I'm a sucker for green liners so I had no choice but to buy Snake Eyes without even seeing it in person. I was not disappointed as it's a gorgeous dark green loaded with shimmer. It's a touch darker than YSL's Jade Black but not quite as blackened as NARS's Night Porter pencil liner, and is more pigmented than the latter. It's also very similar to MAC Jealous Kohl Power liner (long gone as it was part of the 2007 Alexander McQueen collection) but again, more pigmented.
Tatar: More purple than Bobbi Brown's Twilight Shimmer gel, more indigo than YSL's Cherry Black gel liner, Tatar is a dark shimmery cool purple. Of course it looks great with purple shadow but it's also fun with pale pink or grey/silver.
Ubangi: This is easily the prettiest blue liner I own. It's dark but sparkly enough that it shows up on the lid as blue rather than black. While it's my go-to liner for a blue smoky eye, it also works beautifully paired with a simple wash of gold, peach or champagne shadow.
