Accessing a script on a prefab after Instantiate

I would instantiate the prefab from InitScript then have a script attached to the prefab that calls the Init function directly

 // InitScript
 // Instantiate your prefab from here

 var tempColor1 ...
 var tempColor2 ...
 
 var newPrefab : GameObject = Instantiate(prefab, spawnLocation, Quaternion.identity) as GameObject;






 // PrefabScript
 // reference InitScript for tempColor vars and call Init function directly 

 private var initScript : InitScript;

 function Awake()
 {
     // Set up the reference to InitScript
     initScript = FindObjectOfType(typeof(InitScript));
 }

 function Start()
 {
     Init(i, initScript.tempColor1, initScript.tempColor2);
 }

 function Init(...)
 {
     ...
 }
 

Okay thanks. I see what I've been doing wrong. I've been looking at Unity sort of inside out, I think because of how the hierarchy window looks. I've been treating sprites as models ins$$anonymous$$d of as views, and the empty game objects at the top as views ins$$anonymous$$d of models/controllers. Now I see why I was so confused and things weren't working the way I was expecting.
