Random colour on object

Hi guys,

i have this code that instantiates a game object (a TEXT) when ever i click a button. What code do i write, so that when ever it is instantiated, it is a random colour instead of its default (white)?

Thanks

public class OnClickPopUp : MonoBehaviour {

 public GameObject popUp; // prefab to instantiate
 public Canvas canvas; // father canvas
 public Vector2 position;
 

 public void PopUP ()

 {
     
     position.x = UnityEngine.Random.Range(0, Screen.width);
     position.y = UnityEngine.Random.Range(0, Screen.height);
     GameObject clone = (GameObject)Instantiate(popUp, position, Quaternion.identity);
     clone.transform.SetAsLastSibling();
     clone.transform.SetParent(canvas.transform);
     
     Destroy(clone, 0.2f);
 }  }
