Ping Pong Wait Between

I am trying to ping pong between two colors, and once it gets to one end to wait a few seconds, but I am unable to figure it out. So, once it gets to either black or white to wait a few seconds then keep going. Any thoughts?

Code (csharp):

1.  
2.   float t = Mathf.PingPong(Time.time, Duration) / Duration;
3.   renderer.material.color = Color.Lerp(Color.white, Color.black, t);
4.  

 

try it once

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class test : MonoBehaviour {
5.  
6.     public float duration,durationdivision;
7.     void Start () {
8.  
9.         duration = 1f;
10.         durationdivision = 0.5f;
11.     }
12.  
13.     void Update () {
14.  
15.         float t = Mathf.PingPong(Time.time, duration) / durationdivision;
16.         renderer.material.color = Color.Lerp(Color.white, Color.black, t);
17.     }
18. }
19.  

 

That kind of works, but I need it to go fully black,wait x seconds, then transition in y seconds then wait as fully white for x seconds. IF you do what you said it only stops at one end, can I make it stop at both?


Thank you!
