Easy to distinguish Water and Appeal

Since the default colors are close shades of green and are used as an overlay on top of tiles that have different colors, sometimes they are difficult to tell apart. Changing the Coastal Water / Charming Appeal color to bluish fits the color scheme nicely and makes it easy to distinguish. Does not affect saves or anything else, so you can turn it on and off for previous games or share saves with others who don't have the mod with no issues.
