On a map what color is for water?
When you look into an ocean or a lake, the water looks like it's blue. But, up close, water isn't really blue. It's only blue when you look at it in big groups, (like an ocean or a lake, a pond etc.), because the sky is blue, so the color of the sky makes a blue reflection on the water, making it look blue. So, on a map, if you drew water as clear, nobody would be able to tell there was anything there at all! So, water on a map is drawn blue instead.

What color is water?
Pure water has a slight blue color to it. See the Web Links below for the explanation.Note that while water does have a slight bluish color, it is mostly transparent. This is because the molecule does not absorb any light in the visible region of the electromagnetic spectrum (no light that we can see).What most often gives water its color, for instance in a lake, river, or ocean, is not the color of the water itself, but rather the color of things in it, like plants or seaweed, sediment, or other substances. Also, reflection off the surface of the water often make the water take on the color of whatever is being reflected.
