10/16 is a deep olive green holographic. There's not much more to say there! It's a nicely pigmented polish and was maybe a titch on the thicker side, but nothing difficult to work with. Usually I make a quick note if I used two coats, so I think I must have used three here, though I feel like two would have been fine. I don't have much more to add-- I didn't have any issues with this!
Hey, another gorgeous green! 10/16 is definitely dark, but it doesn't veer into black territory and works well for the darker colors we see in the fall and winter months. I feel like photos don't capture it as well as I would have like, but it's very pretty!
