set color before instance

Unity Engine

Hi

How would I set the color property of an instance before I instantiate it?
At the moment, since the same material is shared between all instances, when I click on my color changer GUI, all the instances change to the set color. I want the instances that are already created to remain the same, while the next instantiation(s) to have the color I set through the GUI.

My current color changer script is just a selection grid with color swatches instead of labels.

var randomObject : GameObject;

var selectionGridInt : int = 0;
var icons : Texture[];

function OnGUI () {
	selectionGridInt = GUI.SelectionGrid (Rect (Screen.width - 40, Screen.height / 2 - 230, 30, 230), selectionGridInt, icons, 1);
    
    switch(selectionGridInt){
		case 0:	    
			randomObject.renderer.material.color = Color.black;
			break;
		case 1:
			randomObject.renderer.material.color = Color.red;
			break;
		case 2:
			randomObject.renderer.material.color = Color.yellow;
			break;
		case 3:
			randomObject.renderer.material.color = Color.green;
			break;
		case 4:
			randomObject.renderer.material.color = Color.blue;
			break;
		case 5:
			randomObject.renderer.material.color = Color.cyan;
			break;
		case 6:
			randomObject.renderer.material.color = Color.magenta;
			break;		
	}    
}

Managed to do it by setting another object’s color “colorCube” and then placing this line of code on the prefab.

function Start () {
    	renderer.material.color = GameObject.Find("colorCube").renderer.material.color;
    }

    switch(selectionGridInt){
// etc.

Instead of all that, just use an array:

var colors = [Color.black, Color.red, Color.yellow, Color.green, Color.blue, Color.cyan, Color.magenta];

function OnGUI () { 
   selectionGridInt = GUI.SelectionGrid (Rect (Screen.width - 40, Screen.height / 2 - 230, 30, 230), selectionGridInt, icons, 1);
   randomObject.renderer.material.color = colors[selectionGridInt];
}
