How to know if 2 tags are same in collision?

Im newbie so im trying to make a color switch game to hone my skill but im having a hard time on how to get a collision with same color so I decided on comparing 2 tag so if they are the same tag I will disable the collision

  private void OnTriggerEnter2D(Collider2D collision)
     {
         
         if (collision.tag == "ChangeColor")
         {
             Destroy(gameObject);
             Destroy(collision.gameObject);
             Instantiate(Players[Random.Range(0, Players.Length)], transform.position, Quaternion.identity);
         }
 
         if (collision.tag == gameObject.tag)
         {
             Debug.Log("does it work this way??");
         }
     }
