Scaling a plane in ExecuteAlways mode removes color

Hello everyone,

I'm having an issue when scaling an object with an [ExecuteAlways] script. Here is the script :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 [ExecuteAlways]
 public class Surface : MonoBehaviour {
 
     private GameObject plane;
 
     [Header("Dimensions")]
     [SerializeField] [Range(1, 100)] private float length;
     [SerializeField] [Range(1, 100)] private float width;
 
     private void Start() {
         plane = GameObject.CreatePrimitive(PrimitiveType.Plane);
         plane.transform.localPosition = Vector3.zero;
     }
 
     private void Update() {
         UpdateDimensions();
     }
 
     // Divides by 10 because a plane with scale 1 is 10 unit squared
     public void UpdateDimensions() {
         plane.transform.localScale = new Vector3(length, 0, width) / 10.0f;
     }
 }

So, whenever I use the slider on length and width value, the scales is actually changed. But the color turns black and I do not understand why. Here is a gif to show you :
