Why is the color component not working?

Hey Unity community,

I’m having trouble with adding color to my objects in my script

Here’s the script (appreciate the help):

using System.Collections;
using System.Collections.Generic;

public class Targetting : MonoBehaviour {
public List targets;
public Transform selectedTarget;

private Transform myTransform;

// Use this for initialization
void Start () {

	targets = new List<Transform> (); 
	selectedTarget = null;
	myTransform = transform;
	AddAllEnemies ();
}

public void AddAllEnemies()
{
	GameObject[] go = GameObject.FindGameObjectsWithTag ("Enemy");

	foreach (GameObject enemy in go)
		AddTarget (enemy.transform);

}

public void AddTarget(Transform enemy)
{
	targets.Add (enemy);
}

private void SortTargetByDistance()
{
	targets.Sort(delegate(Transform t1, Transform t2){
		return Vector3.Distance(t1.position, myTransform.position).CompareTo(Vector3.Distance(t2.position, myTransform.position));
		});
		
	}

private void TargetEnemy()
{
	if (selectedTarget == null) {

		SortTargetByDistance ();
		selectedTarget = targets [0];
	} else {
		int index = targets.IndexOf (selectedTarget);
		if (index < targets.Count - 1) {
			index++;
		}
		else
		{
			index = 0;
		}
		selectedTarget = targets[index];
	}
}

private void SelectTarget()
{
	selectedTarget.GetComponent<Renderer>().material.color = Color.red;
}

// Update is called once per frame
void Update () {

	if(Input.GetKeyDown (KeyCode.Tab)) {
		TargetEnemy ();
	}
}

}

Thanks for the help!

From the script above it looks like you never call SelectTarget(), which is responsible for the color change.
