Glazing bowls

I usually glaze my bowls in stages to avoid mistakes. But now I am stuck; I covered the fish with a mottled blue crystal glaze; the shells are predictably white. But what colour shall the sea be?
I am so tempted to use a rich orange! The same glazes I use for my pomegranates;

Which is actually a mixture of Botz Lava and Koralle. Or should I go for a predictable blue-green?

Decisions, decisions….
