Nabi #10 is a medium navy blue polish. It wasn't as dark as I was expecting it to be, but it is really pretty once on the nail. It actually wasn't the best shade of blue for my skin tone, but I loved it anyways! Photos below are 2 coats of polish over one coat of Instant Artificials. My NYC Grand Central Station did dull the holo when I used it as a top coat, so photos below are without any top coat.
