Formula X Prismatic Nail Lacquer ($12.50 for 0.40 fl. oz.) is described as a “emerald micro-glitter in sheer emerald.” It’s a muted, dusty, cool-toned green with lighter green and medium green micro-glitter. It was noticeably sheer with visible nail line after two coats. It didn’t apply as evenly as it should have. Obsessive Compulsive Cosmetics Man by Man (P, $10.00), Zoya Giovanna (P, $9.00), and Dior Samba (794) (LE, $24.00) are all darker and brighter. Obsessive Compulsive Cosmetics Chimera (P, $10.00) is less cool-toned. Zoya Zuza (P, $9.00) is still brighter. See comparison swatches.
