Despite Zoya rating this a 5 on their opacity scale (5 being the most opaque), I found this to be slightly sheer in the first coat, and needed three to get it to the opacity I wanted. But it goes on very easily, so I didn't have any issues applying it.
Artificial light (flash):
This is such a pretty blue-- I love the dusty, steely quality it has. It's a perfect stormy blue any time of year!
