I got an email from Rescue Beauty Lounge saying that they're introducing an opaque dark navy called Dead Calm. There's no photo on the site yet, but it might be what you're looking for. I can't wait to see their new Under The Stars, which is supposed to be sparkly like Revamp (now called Black Russian) but in navy.thanks onyx and fendi! looks like i'm still on the hunt for a flat navy blue polish!!
