Color Array in C#

Hi guys, I have this code:

 using UnityEngine;
 using System.Collections;
 
 public class ScriptEnemy: MonoBehaviour {
     public int numberOfClicks = 2;
     public float fWaitTime = 2;
     public color[] shapeColor;
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         Vector3 varPosition;
         if (numberOfClicks <= 0 ){    
             varPosition  = new Vector3(Random.Range(-6,6),Random.Range(-4,4),0);
             RespawnWaitTime();
             transform.position = varPosition;
             numberOfClicks = 2;
         }
     }
     
     IEnumerator RespawnWaitTime() {
         transform.renderer.enabled = false;
         ChangeColor();
         yield return new WaitForSeconds(fWaitTime);
         transform.renderer.enabled = true;
     }
     
     void ChangeColor() {
         if (shapeColor.length > 0){
             int newColor = Random.Range(0,shapeColor.length);
             renderer.material.color = shapeColor[newColor];
         }
     }
 }

And Im getting this error

Assets/Scripts/ScriptEnemy.cs(7,16): error CS0246: The type or namespace name `color' could not be found. Are you missing a using directive or an assembly reference?

I want to set an array of colors visible on the inspector. Can someone help me?. The array length can be X, I don't know how many colors are going to be drawn.
