Can't change fog color!

Hi there.

I ran into this problem: i am unable to change the fogs color, not with the scripted palette, not even without a set variable, giving it color manually in script. It always stays an ugly brown shade. Here is my script:

*var fogColor = Color (1,1,1,1);
private var defaultFog = RenderSettings.fog;
private var defaultFogColor = RenderSettings.fogColor;
private var defaultFogDensity = RenderSettings.fogDensity;
var noSkybox : Material;
var normalSkybox : Material;
function Start () {
//Set the background color
camera.backgroundColor = Color (1, 1, 1, 1);
}
function OnTriggerEnter ( other : Collider) {
if (other.gameObject.tag == "WaterCollider") {
RenderSettings.fog = true;
RenderSettings.fogColor = fogColor;
RenderSettings.fogDensity = 0.04;
RenderSettings.skybox = noSkybox;
}
}

function OnTriggerExit ( other : Collider) {
if (other.gameObject.tag == "WaterCollider") {
RenderSettings.fog = defaultFog;
RenderSettings.fogColor = defaultFogColor;
RenderSettings.fogDensity = defaultFogDensity;
RenderSettings.skybox = normalSkybox;
}
}*

All other functions work fine ,so it only triggers when entering the tagged colliders, and it reverts when the collider are left. But its no good withour a blue-ish colour,im not swimming in sewer water! Any help would be greatly appriciated.

Thank you for your time.
