Under a Blue Sun swims a Golden Sea

All water worlds are twins. They have to be. The same way that the sky just has to be blue.

However; for the sky to be blue, the sun must be gold. And, if the Sun where blue, then the sky would be gold; and the good old sea always matches too.

Turquoise is the shadow of yellow. Like the Earth is the twin of the moon. The sea and the sky are themselves twins. And; the ocean needs its moon to keep it moving... grinding out the tides forever, providing sufficient kinetic energy to keep the sacred liquid boiling precisely in the right context for life to be fostered. If it lost its moon, the water-world would freeze and become an ice-world.

But the colorless nature of air, and the transparent poetry of water, get their shaded hue from being more than mere shadows of the Sun's light. For sand can tint the ocean aquamarine; just as dust and smoke can burn the sky sienna-crimson, magenta-peach, and African orange.

On the planet Wyveniah, the seas are golden brown, and the skies are lemon flavored. And, the mother star burns a luminescent blue, known as 'Rigel', a colour that holds special religious significance if it reaches a particular shade precisely in between aquamarine and turquoise.

I have only written two chapters, and will not mind at all if people feel inspired by what I have written, and add onto it.
A good idea for schoolteachers to read the first two chapters to the kids and see what comes out of it!
