I’m about a kilometer from the ocean right now (I’m standing in front of the window through which I can see it), and it’s a partly cloudy day. When the sky is clear (as it was five minutes ago), the ocean is a rich, saturated blue or even teal. When it’s cloudy (as it is currently), I can see that it’s a cool gray color. I might call it a very dark, desaturated cyan at most. So from my observation it has to be the opposite: the relative blueness of the ozone and the water must be the less dependent factor, and the color of the sky the more dependent one.

It’s tricky, though. I guess I might be in a place with weird salinity or plankton or something.
