The Dark Green Sea is spot on now as that is how it looks when you are out on it or directly over it Especialy around the English channel and the British coast.
The visability throught the water is seldom crystal clear in warmer months due the abudance of marine organisms .
Winter can bring the clearest seas but only provided the weather has been light on wind and air temps are low.
I have worked in fishing boats on the south coast and had air flights over the same areas in most seasons.
What is noticable is the height above ,or angle you are looking from dictates what shades you see.
Stood on a beach or in a boat the sea looks green directly in front of you but as you look further away into the distance depending on light intensity it reflects the sky above ether blue,blue green,blue black or silvery grey.The ecceptions are in rough weather or when the angle to the sun is shallow where you will experience glare and brightness on the water.
Saying that I flew back from Spain in the winter months with clear skys and over the Channel the sea looked flat and black green or black blue.I could clearly see the larger white topped ferries crossing way below.I think the Screenshots are pretty accurate that people have posted
The land colors brightness and shading are still unrealistic to me.
