PlayerPrefs for Random Materials

Okay, so below there will be a block of text, and I'm sorry, but hear me out: There's one scene which generates the "world" using a 2d array. Then, the next scene is the game itself, which is using these values to create colors for materials. According to the Debug Logs i had, the Material.SetColor() part is where it breaks. The material is completely white, not even reacting to shadows, but when i click the material in the inspector, it is the color that it's supposed to be. I tried changing the EmissiveColor_ but the effect stays the same. Here's the code.

worldGenerator

 public class worldGenerator : MonoBehaviour
 {
 //46 46 100
 public int[] matr = new int[10];
 public int[] matg = new int[10];
 public int[] matb = new int[10];
 public int[] mathrd = new int[10];
 public int[] matrct = new int[10];
 public string[] matt = new string[10];
 public int[,] world = new int[100,100];
 public int[] matx = new int[10];
 public int[] maty = new int[10];
 
 // Start is called before the first frame update
 void Start()
 {
     for (int i = 0; i < 5; i++)
     {
         matr[i] = Random.Range(0, 101);
         matg[i] = Random.Range(0, 101);
         matb[i] = Random.Range(0, 101);
         mathrd[i] = Random.Range(1, 6);
         matrct[i] = 0;
         matt[i] = "wood";
         matx[i] = Random.Range(0, 101);
         maty[i] = Random.Range(0, 101);
     }
 
     for (int i = 0; i < 5; i++)

         matrct[i + 5] = 1;
         matt[i + 5] = "rock";
         matx[i + 5] = Random.Range(0, 101);
         maty[i + 5] = Random.Range(0, 101);
     }
 
     for (int i = 0; i < 100000; i++)
     {
         int j = 0;
         foreach (int item in matx)
         {
             world[matx[j], maty[j]] = j;
             matx[j] += Random.Range(-1, 2);
             if (matx[j] >= 100 || matx[j] <= -1)
             {
                 matx[j] = 100 - Mathf.Abs(matx[j]);
             }
             maty[j] += Random.Range(-1, 2);
             if (maty[j] >= 100 || maty[j] <= -1)
             {

         }
