Leap: Touch object multiple times, different behavior.

Essentially, I want to be able to touch object multiple times and have the object behave differently each time.
When I touch it the first time it would turn red ,the second time it would turn blue and the third time it will turn back to white.
Touch 0: White
Touch 1: Turns Red
Touch 2: Turns Blue
Touch 3: Turn back to White
This is my code, but the issue is that the OnTriggerEnter happens every frame so the shape would turn from white to blue with out turning red..etc

Here is my code:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class ShapeScript : MonoBehaviour {
5.  
6.     public bool touched;
7.     public bool touched2;
8.     public bool enter;
9.  
10.     // Use this for initialization
11.     void Start () {
12.         touched = false;
13.         touched2 = false;
14.         enter = false;
15.         //InvokeRepeating ("UpdateColor", 0, .7f);
16.    
17.     }
18.     private bool IsHand(Collider other)
19.     {
20.         if (other.transform.parent && other.transform.parent.parent && other.transform.parent.parent.GetComponent<HandModel>())
21.             return true;
22.         else
23.             return false;
24.     }
25.  
26.     IEnumerator OnTriggerEnter( Collider col){
27.  
28.         if (IsHand(col)) {
29.             enter=true;
30.             //Debug.Log( touched +" " +touched2);
31.             if(!touched && !touched2 && enter){
32.                 touched=true;
33.                 touched2=false;
34.            
35.  
36.             }
37.             else if(touched && !touched2 && enter){
38.                 touched=false;
39.                 touched2=true;
40.  
41.             }
42.             else if(!touched && touched2 && enter){
43.                 touched=false;
44.                 touched2=false;
45.             }
46.             yield return new WaitForSeconds(1);
47.  
48.            
49.         }
50.  
51.  
52.  
53.     }
54.     void OnTriggerExit(){
55.         enter = false;
56.  
57.     }
58.    
59.     // Update is called once per frame
60.     void UpdateColor(){
61.  
62.         if (touched) {
63.             gameObject.GetComponent<Renderer> ().material.color = Color.red;
64.  
65.  
66.         } else if (touched2) {
67.             gameObject.GetComponent<Renderer> ().material.color = Color.blue;
68.         }
69.         else {
70.             gameObject.GetComponent<Renderer> ().material.color = Color.white;
71.         }
72.    
73.     }
74.  
75.     void Update(){
76.        UpdateColor ();
77.         if (touched && HandScript.enable  ) {
78.             gameObject.transform.Rotate(Vector3.up, HandScript.handRotation.y);
79.  
80.  
81.         }
82.         if (touched2 && HandScript.enable) {
83.             gameObject.transform.Rotate(Vector3.left, HandScript.handRotation.x);
84.         }
85.  
86.     }
87. }
88.  

There is a lot of overlap because I've been trying to find a fix.

Any help would be appreciated!!

 

Bump!
