NYX Lime Salon Formula Nail Polish ($4.00 for 0.52 fl. oz.) is a bright lime green with chartreuse shimmer. It’s vibrant and the right mix of shimmer and metallic, because you get some of the brush strokes of a metallic finished polish but they’re easy to control to get into straight line. China Glaze Cha Cha Cha is much greener, while Butter London Dosh is a darker green. China Glaze Electric Pineapple is similar in color but has a cream finish. Illamasqua Radium is a touch greener and while it also has shimmer, it’s much subtler and green rather than chartreuse.
