Thank you very much to everyone for participating in this game and for sharing it, I always learn a lot with you.
Regarding the question of @Roger.Wilco
Here is another Play Raw with a photo from the same day in which you can see that the sea has different shades of blue depending on the depth of the sea in that place. In the deep areas, the blue of the sea is dark, while as the depth decreases, the blue becomes more green.
In this photo, only in the upper left part, where you can see some rocks that are slightly submerged in the sea, the blue would have a more greenish hue, in the rest the blue is darker.
Anyway, in my opinion, we are playing, any color is valid.
All the best.
