MAC Submerged Nail Lacquer ($17.50 for 0.34 fl. oz.) is described as a “dark teal chrome.” It’s a medium-dark, navy blue with a teal micro-shimmer and flash. This one didn’t apply as nicely as the other two, as there were visible brush strokes and some unevenness, though the color coverage was opaque after two coats. Color Club First Looks (P) is much darker. China Glaze Deviantly Daring (LE, $7.50) is darker, more teal. See comparison swatches / view dupes.
