Bobbi Brown Turquoise Nail Lacquer ($18.00 for 0.37 fl. oz.) is described as a “flat vibrant turquoise.” It’s a little bluer than what I think of when I hear “turquoise,” but it’s not a true blue–definitely a blue-teal. (Even if you google “turquoise,” you’ll see it varies quite a bit from green to blue.) It has a cream finish. Estee Lauder Teal Topaz is lighter, less blue. Illamasqua Muse is darker, bluer. Orly Viridian Vinyl is a smidgen less blue. Butter London Artful Dodger is similar as well, though it, too, is less blue.
