Changing color on a material through script

Question

Newish to unity here.

I need to change the color of a gameobject designed with a raycasthit.

Roughly:

RaycastHit hit;

hit.collider.GetComponent().GetComponent().SetColor("_white", Color.white);

Upon testing that code, I keep getting :

'' there's is no material attached to the gameobject, but a script is trying to access it''.

I drag-and-drop'd my material onto my gameobject, I tried creating public variable in the script ( of the game object, material, renderer... everything) and using the inspector to associate them... nothing.

I must be missing something obvious, yet can't see it.

Thanks for your time.

Roughly :

 void Update () 
     {
         RaycastHit hit;
         Ray ray= Camera.main.ScreenPointToRay (Input.mousePosition);
         if (Physics.Raycast (ray, out hit)) {
             hit.collider.GetComponent<Renderer> ().material.SetColor ("_Color", Color.white);
         }
     }

So if mouse enters above object it's material color will change to white.

Thanks, the big problem : i used GetComponent().SetColor... ins$$anonymous$$d of .material.SetColor...

As expected, a simple detail that troubled me for waaay too long.
