SpriteRenderer is gone when I change in script.

So, I had an idea for making a game that include characters customization, and I want to make user can actually change the character's body color. But, I have a problem in here. When I drag the sprite that I want to render, it is just gone. This is the picture of it :

Here is how the spriteRenderer object looks like :

But in the gameplay, the body doesn't show up, it's just the other sprite that showed up!

This is the code :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 
 public class skinColor : MonoBehaviour {
 
     public GameObject panel;
 
     public SpriteRenderer body;
 
     public Color[] colors;
     public int whatColor = 1;
 
     void Update()
     {
 
         for(int i=0; i<colors.Length; i++)
         {
             if(i == whatColor)
             {
                 body.color = colors[i];
             }
         }
     }
 
     public void ChangePanelState(bool state)
     {
         panel.SetActive(state);
     }
     public void ChangeBodyColor(int index)
     {
         whatColor = index;
     }
 }
