Color of the friendly player's name

Hi!
I have 3 races in my game which accord to 3 palyer tags (PlayerRace1, PlayerRace2, PlayerRace3). Every race has certain color for character’s name above head but i need character one race to see green color above head but if character’s are in different teams they see Race color.

public class ObjectLabel : MonoBehaviour
{
    private Transform _go;

    void Awake()
    {
        _go = this.transform.parent;
    }

    void Start()
    {

        if (_go.tag == "PlayerRace1") //0 255 96 255 ---> for friends!
        {
            GetComponent<GUIText>().color = new Color32(192, 184, 96, 255);
        }

        else if (_go.tag == "PlayerRace2")
        {
            GetComponent<GUIText>().color = new Color32(136, 91, 229, 255);
        }

        else if (_go.tag == "PlayerRace3")
        {
            GetComponent<GUIText>().color = new Color32(60, 165, 191, 255);
        }
    }

    void Update()
    {
        Vector3 cameraRelative = Camera.main.transform.InverseTransformPoint(_go.FindChild("AboveGUIPosition").position);

        if (_go.gameObject.tag.Contains("Player"))
        {
            if (cameraRelative.z > 0)
            {
                Positioning();
            }

            if (_go.tag == "PlayerRaceEnemy")
            {
                GetComponent<GUIText>().color = new Color32(219, 18, 85, 235);
            }
        }

        else if (_go.gameObject.tag == "Creature")
        {
            if (cameraRelative.z > 0)
            {
                Positioning();
            }
        }
    }

    void Positioning()
    {
        Vector3 pos = Camera.main.WorldToViewportPoint(_go.FindChild("AboveGUIPosition").position);
        transform.position = pos;
    }
}

So how to do this if every character has his own GUIText? Should i use Raycast or not?

Hard to say exactly without knowing what the other tags are in your game but probably something like

public class ObjectLabel : MonoBehaviour
 {
     private Transform _go;
 
     void Awake()
     {
         _go = this.transform.parent;
     }
 
     void Start()
     {
 
         if (_go.tag == "PlayerRace1") //0 255 96 255 ---> for friends!
         {
             GetComponent<GUIText>().color = new Color32(192, 184, 96, 255);
         }
 
         else if (_go.tag == "PlayerRace2")
         {
             GetComponent<GUIText>().color = new Color32(136, 91, 229, 255);
         }
 
         else if (_go.tag == "PlayerRace3")
         {
             GetComponent<GUIText>().color = new Color32(60, 165, 191, 255);
         }
         else if (_go.gameObject.tag.Contains("Enemy")) // enemy colour
         {
             GetComponent<GUIText>().color = new Color32(219, 18, 85, 235);
         }
     }
