Change color of cloned prefab objects

I am trying to create a grid of tiles and basically have them all different colors(I have an array of 4 colors to choose from). I have been working on it for hours and looking online and nothing I do seems to make it change colors from the default prefab color.

I have a script that is creating the grid and the tiles. I have tried a few different ways(both are there, one is commented out) and it always stays the same color(it isn’t one in the array, it’s the default color of the prefab).

`void Start () {

	//Set colors for tiles
	colors[0] = new Color(242, 103, 103); //Pink
	colors[1] = new Color(80, 206, 196); //Blue
	colors[2] = new Color(147, 206, 80); //Green
	colors[3] = new Color(238, 174, 79); //Orange

	//Create the number of tiles needed
	GameObject[] tiles = new GameObject[numRows * numColumns];

	for (int i = 1; i <= tiles.Length; i++) {
		tiles[i-1] = Instantiate(tilePrefab) as GameObject;
		tiles[i-1].transform.SetParent(gameCanvas.transform);
		tiles[i-1].transform.position = new Vector3 (x, y, 0f);
		//tiles [i - 1].GetComponent<Renderer> ().material.color = colors [3];
		Renderer rend = tiles[i-1].GetComponent<Renderer>();
		rend.material.color = colors [3];
		x += 320;

		if (i % 3 == 0) {
			x = 300;
			y -= 320;
		}

	}`

Everything I find online does not work or is either outdated like renderer.material.color

edit: I apologize for the code being like that, it looks organized in the text box as I edit it, but when I save, it bunches it into a paragraph

I found my mistake! After further looking online and playing around on Unity, I was using a GameObject for my image, however I needed to change it from GameObject to Image in my code and include “using UnityEngine.UI” and then tiles[i-1].color = Color.red worked.

Sorry for being a noob!
