Saving colors of multiple mesheseach having multiple materals

I need a function where I can pass Gameobject and I have a global static variable SavedColor[][] .

I had chosen the SavedColor as a 2D array as my gameobject can have multiple meshes , each mesh has different materials having different colors each .

private static Color[,] SavedColor; private static bool is_saved = false; void Start() { SavedColor = new Color[100,100]; }

void Save_Color_Full(GameObject obj) { // Find all the renderers Renderer[] rs = obj.GetComponentsInChildren(); //Debug.Log(rs.Length);

     for (int i = 0; i < rs.Length; i++) 
     {
         int j = 0;
         Material[] ms = rs [i].materials;
         foreach (Material m in ms) 
         {

             Saved_Colors [i,j] = m.color; 
             rs [i].materials [j] = m;
             //Debug.Log (Saved_Colors[i,j]);

             j++;

         }

     }
     save_color = true;

 }

void Load_Color_Full(GameObject obj) { save_color = false; Renderer[] rs = obj.GetComponentsInChildren();

     for (int i = 0; i < rs.Length; i++) 
     {
         int j = 0;
         Material[] ms = rs [i].materials;
         foreach (Material m in ms) 
         {
             m.color = Saved_Colors [i,j]; 
             rs [i].materials [j] = m;

             j++;

         }

     }

 }
