GOSH's Ocean is a lovely green/blue with winks of purple in the right light shade.
It is a bit on the thick (bordering gloopsome) side but this allows a suitable opacity in 2 licks of the brush.
I paired it with a Japanese glitter polish that I had lurking around. I don't often see a nice blue glitter and this one has served me very well for the past couple of years. The shade is BU-20 from KATE (owned by Kanebo).
I think the pair of polishes compliment each other nicely and tell a silent tale of adventures upon shimmering seas very well. A bit of imagination required.
