Sky is a faded blue with a hint of green with a green-gold shimmer. It has swirls of light-medium green, electric blue, and cobalt blue. The color payoff is sheer when used dry, and it’s better when wet, but it’s still not fully opaque. Urban Decay Shattered is a bit more teal. Guerlain Les Ombres de Nuit doesn’t have the same gold shimmer.
