I'm using the clip water and it works (splashes and ripples when shot) but it's completely invisible. How can I give it a color? Such as a grayish color or something - kind of like what the water looks like in Necro Forest by Megadeth 

Water clip isn't actually a water material - its a clip meaning its a physical entity that the player interacts with (similar to the normal clip texture that is invisible and the player collides with). You need to create a brush with an actual water texture, they are the blue grid looking textures - they don't look like water in radiant but when you compile they will.

Clip textures are invisible ingame but have different properties (goes ontop of actual texture) depends on intended use. Like for some examples blocking bullets, or players, or zombies, or sound like metal, splash like water & many more. Hope you discover more & happy mapping
