Changing a material on a particle on collision

Question

So basically I want to change the particles materials colour on my prefab when it hits the transform with tag Shield and I've tried just about everything I can think of but I cant seem to get at the right spot. here's my code at pretty much everything I have tried any help would be amazing hope I was at least somewhat close to solving somewhere. so in the image attached I want the green tint colour to be changed to lets say red on collision and only the one prefab that collided with the game object not all bullets turning red. any help would be absolutely alt text amazing

 public Material myColor;
 public bool armed = false; // when true it will explode on impact
 void OnCollisionEnter (Collision col)
 {
     if (col.transform.tag == "Player") {
         Destroy (gameObject);
         // start explosion
         // decrement player health
     } else    if (col.transform.tag == "Shield") {
         armed = true;
         print ("armed " );

// print (GetComponentInChildren ().name); // ParticleSystem ps = GetComponentInChildren ();

         //Material pm = getcom GetComponentInChildren<Material> ();
         //print (pm.name);

// print (ps.GetComponent().material.GetColor("_TintColor").ToString()); // Renderer r = ps.GetComponent (); // r.material.SetColor ("_TintColor", new Color(1f,0f,0f,1f)); // print (ps.GetComponent().material.GetColor("_TintColor").ToString());

         //GetComponent<Renderer> ().material.SetColor("_TintColor", new Color(1f,0f,0f,1f));

         //Material[] m = ps.getcom ();
         //print ("mmmm " + m.Length);
         //print (GetComponentInChildren<ParticleSystem> ().GetComponent<MaterialPropertyBlock>());


         //gameObject.GetComponentInChildren<ParticleSystemRenderer>().material = newMat;

You need to access the 'material' component in the 'ParticleSystemRenderer'. Here's a quick script I wrote up. This should do the trick!

 // The particle system you want to change
     public GameObject particle;
     // The new material you want to apply to the particle system
     public Material newMaterial;
 
     private void Start()
     {
         // Access the 'ParticleSystemRenderer' component, and change the material to 'newMaterial'.
         particle.GetComponent<ParticleSystemRenderer>().material = newMaterial;
     }
