Changing Water color on the minimap?

I know how to change the water color itself when terraining, but is there a way to make it so that the minimap reflects this color change? If the water is jet black I don't want it to be a calm blue on the minimap.

Well, the water level is set at -1 and the surface is flat. If you adjust the camera just above the surface of the water, all you'll see is a flat line. The same goes for deep water.

Maybe you have to customize the terrain of the water, yourself. How you do that; I have no idea.

Well you can export the minimap - and then change its color in photoshop, or another image program..

I dont know if there is another way.
