China Glaze Splish Splash Nail Lacquer ($6.49 for 0.50 fl. oz.) is described as a “bright sky blue shimmer.” This is a brightened medium sky blue with fine, pale white-blue shimmer. It’s a very swimming pool-inspired blue, I’d say. It’s not quite bright enough to be called a neon, but it’s certainly not subdued. I thought this would be readily duped, but out of all these blues, nothing came close enough. At a glance, China Glaze Blue Iguana seemed like a possibility, but upon closer inspection, it’s much, much darker, and it has purple shimmer. I’d love to hear from you if you have any dupe possibilities!
