NARS Disco Inferno Nail Lacquer ($18.00 for 0.50 fl. oz.) is described as an “iridescent silver green.” It’s a gray-tinged base with threads of silver shimmer. There is a very slight pink tinge when nails are angled, but it’s very subtle. MAC Ascension has finer shimmer and a stronger pink-purple duochrome. It looks a lot like Wet ‘n’ Wild Gray’s Anatomy, which seems to have more of a green tinge and finer shimmer.
