Unity 5 Syncvar not working

Question

I have a cube in my scene. I want to change its color and I wanna server and all players to see it in this color. I have attached script on the cube:

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

public class Cube : NetworkBehaviour
{
    [SyncVar(hook = "OnColorChanged")]
    public Color myColor;

    void OnColorChanged(Color value)
    {
        GetComponent<Renderer>().material.color = myColor;
        Debug.Log(value + "," + myColor);
    }

    void Update()
    {
        Debug.Log(myColor);
    }
}

I run GameObject.FindWithTag("cube").GetComponent<Cube>().myColor = Color.red;this in my host script when I want to change the color of the cube, but nothing happens.

From the documentation on SyncVar:

• These variables will have their values sychronized from the server to clients in the game that are in the ready state.

Its possible that you are applying the change on a client.

SyncVars only sync changes from the server to the clients. If you want to update a SyncVar from a client, make the client send a Command from the client to the server that updates the value.
