How do I change the color of water for my map?

[KommissarReb]

I want to change the color of the water on my map to brown like Nal Hutta's water from SWTOR. I watched , but he never elaborated what specific values change the color, or which numbers translate to which color for "RefractionColor" or "ReflectionColor".

"ReflectionColor" controls the colour of the reflections in the water and "RefractionColor" controls the colour of things under the water.
