NARS Thasos Nail Polish ($20.00 for 0.50 fl. oz.) is described as a “mint green.” It’s a light-medium, sea foam green with a cream finish. It was opaque after two coats, and the consistency of the polish wasn’t too thick or too thin. It was really close to being opaque after one coat, which was impressive, but what was even more impressive was the lack of streakiness even on that initial coat. This shade lasted for seven days with minor tip wear. MAC In the Limelight (LE, $16.00) is bluer. Illamasqua Nomad (P, $17.00) is darker, brighter. China Glaze Keep Calm, Paint On (LE, $7.50) is greener, warmer. Zoya Wednesday (P, $9.00) is darker. Butter London Fiver (P, $15.00) is lighter. See comparison swatches / view dupes.
