Batignolles is described as a "cross between a sky and turquoise blue." It's a light-medium, green-leaning aqua with subtle, warm undertones and a cream finish. It was opaque after two coats with a consistency that wasn't too thick or too thin, so it spread easily across the nail without pooling along the edges. When I tested this shade for wear, it lasted for seven days with minor tip wear but no chipping. NARS Thasos (P, $20.00) is lighter, warmer (85% similar). Illamasqua Nomad (P, $17.00) is brighter (80% similar). Zoya Wednesday (P, $9.00) is darker (90% similar). See comparison swatches / view dupes side-by-side.
