I need help with Door animations

Hi I'm creating my first game and I've been learning A LOT with this project but i'm stuck now. I was doing a key and door system that I found from Codemonkey. and it all worked untill i decided to change the colors. since i changed the colors now the 3 doors wont share the same animation. the problem is that i cant figure out how to code:

"if the green door is opened, play the 'GreenDoorOpen' animation;"

"if the blue door is opened, play the 'BlueDoorOpen' animation;"

"if the red door is opened, play the 'RedDoorOpen' animation; "

The Door Script:

 public class KeyDoor : MonoBehaviour
 {
     public Animator anim;
 
     [SerializeField] private Key.KeyType keyType;
     public Key.KeyType GetKeyType()
     {   
         return keyType;
     }
 
     public void OpenDoor()
     {
         anim.Play("DoorOpen");
     }

The KeyHolder Script:

 public class KeyHolder : MonoBehaviour
 {
     private List<Key.KeyType> keyList;
 
     private void Awake()
     {
         keyList = new List<Key.KeyType>();
     }
 
     public void Addkey(Key.KeyType keyType)
     {
         Debug.Log("Added Key: " + keyType);
         keyList.Add(keyType);
     }
 
     public void Removekey(Key.KeyType keyType)
     {
         keyList.Remove(keyType);
     }
 
     public bool Containskey(Key.KeyType keyType)
     {
        return keyList.Contains(keyType);
     }
 
 
     private void OnTriggerEnter2D(Collider2D collider)
     {
        Key key = collider.GetComponent<Key>();
        if (key != null)
        {
            Addkey(key.GetKeyType());
            Destroy(key.gameObject);
        } 
        KeyDoor keyDoor = collider.GetComponent<KeyDoor>();
        if (keyDoor != null)
        {
            if (Containskey(keyDoor.GetKeyType()))
            {
                //Currently holding Key to open this door
                Removekey(keyDoor.GetKeyType());
                keyDoor.OpenDoor();
                
            }
        } 
 
     }
 }

The key script:

 public class Key : MonoBehaviour
 {
     [SerializeField] private KeyType keyType;
 
    public enum KeyType
    {
        Red,
        Green,
        Blue
    }
 
    public KeyType GetKeyType()
    {
        return keyType;
    }
 }
