[R&F] Please make the coastal tiles more discernible from the ocean tiles

[KyivanRusCivPlease]

If possible without sacrificing the beauty of the water in Civ 6, please make the coastal tiles more discernible from the ocean tiles by increasing color contrast, since I find myself using the strategic view to move my galleys and quadriremes before I am able to navigate the ocean. Also it would be great to make the grid more visible on water for making it easier to count water tiles e.g. for planning Entertainment Complexes.
