Saphir

The grey undertone makes it look almost moody in low light, then it shifts to a true azure in the sun. Two coats and it's fully opaque, which is rare for a blue like this.

The blue is stunning, that grey undertone gives it a really elegant depth instead of looking too bright. It goes on smoothly enough, but I did need two coats to get the true sapphire color to pop. Still, it's a beautiful shade for the price.
