Changing the Color of an object during runtime using ray casts

Just want it so that when the ray cast hits the cube (with a red material) it turns to blue. I am successfully using the ray cast, but getting no result with change colour.

Code (csharp):

1. //Raycast against tiles
2.     var fwd = transform.TransformDirection(Vector3.forward);
3.     var hit : RaycastHit;  
4.    if(Physics.Raycast(transform.position, fwd, hit, 10))
5.    {
6.       Debug.Log("Hit");
7.         if(hit.trigger.gameObject.name == "Red")
8.         {
9.          print ("Hit Red Box");
10.         renderer.material.color = Color.blue; //Obviously didn't work
11.         }  
12.    }
13.    
14.    Debug.DrawRay(transform.position, fwd * 10, Color.green);
15.    
16. }  

Thanks, guys.

 

Try this one, because you were not trying to change the color on the object you hit, but on the object you were raycasting from.

Code (csharp):

1. hit.collider.renderer.material.color = Color.red;

 

Whenever i get a collision the console comes up saying:
"MissingFieldException: Field 'UnityEngine.RaycastHit.trigger' not found."
