GameObject coloring

Questions & Answers

Hey guys! I'm trying to color the gameobject's area based on what was clicked with the mouse(mouse's Position). the problem is that when I attach this script to my Cube gameobject it doesn't do anything. Do I need to use a shader for it? I'm using Diffuse one.. I also try VertexLit,etc.. but it doesn't solve the problem.

using UnityEngine;
using System.Collections;

class TriangleHighlighter : MonoBehaviour{
    // Use this for initialization
    void Start () {
        MeshFilter meshFilter = gameObject.GetComponent<MeshFilter>();
        Mesh mesh = meshFilter.sharedMesh;
        Color[] vertexColors = mesh.colors;
        for(int i = 0; i < vertexColors.Length; ++i)
        {
              vertexColors *= Color.blue;*
 *}*
 *mesh.colors = vertexColors; // update the vertex colors*
 *}*
 *// Update is called once per frame*
 *void Update () {*
 *}*
*}*
*```*

You'll need to use a vertex coloured shader, like this one:
