Light My Sapphire was a disappointment in formula, not necessarily color. The color is a bluish-black with a subtle silvery shimmer. It's darker than the true deep navy of China Glaze Up All Night but you can definitely tell it's not a black or charcoal gray polish. The problem with this one is the application. It was uneven, gloppy and just plain frustrating. I applaud OPI for taking the steps to rid their polishes of toxic chemicals but if this polish is an indicator, they may want to head back to the lab.
