Changing color of Particles C#

Hi,

What I am trying to do is change the color of my particles which is a prefab attached to my game object. Everytime I press the 'h' key on the keyboard the particle system instantiates. I am trying to change the colors of each particle from white to red by iterating through the array.

I've tried to do this with the following code within an OnTriggerStay function:

//... private Particle[] PlayerParticles; public GameObject ParticlePrefab; // added to the player under its script private GameObject instantiated;

if (Input.GetKey("h") && instantiated == null)
{ instantiated = (GameObject)Instantiate(ParticlcePrefab, transform.position, Quaternion.identity);
PlayerParticles = particleEmitter.particles; // Error for (int i = 0; i < PlayerParticles.Length; i++) { PlayerParticles[i].color = Color.red; } particleEmitter.particles = PlayerParticles;

}

Getting the error:

MissingComponentException: There is no 'ParticleEmitter' attached to the "Player" game object, but a script is trying to access it. You probably need to add a ParticleEmitter to the game object "Player". Or your script needs to check if the component is attached before using it.

I know for a fact that the particle emitter is attached to the gameobject, player. Why would the particle emission happen upon pressing 'h' if it wasnt?
