SyncVar Color is not sync

Questions & Answers
1

I instantiate a game object
And gives him a color
But host-side look, the color does not change
Why is this?

public class NBID : NetworkBehaviour {
	[SyncVar]public Vector3 syncpos;
	[SyncVar]public Color mycol;

	void Update () {
		Move();
		GetComponent<Renderer>().material.color=mycol;
	}
	void Move(){
		if(isServer){
			syncpos = transform.position; 
		}
		if(!isServer){
			transform.position = syncpos;
		}
	}
}


public class S4play : NetworkBehaviour {

	public override void OnStartLocalPlayer () {
		palycol=KPS.color;//'KPS.color' is a static color
	}

	void Update () {
		ccol(mybody,palycol); // 'mybody' is I instantiate objects

	}


	[Client]
	void ccol(GameObject obj,Color col){
		Cmdcol(obj,col);
	}

	[Command]
	void Cmdcol(GameObject obj,Color col){
		obj.GetComponent<NBID>().mycol=col;
	}

}

Finally, I found the cause of the problem

I should rewrite ‘Renderer’ rather than ‘[SyncVar] public Color mycol;’

	[Client]
	void ccol(GameObject obj,Color col){
		Cmdcol(obj,col);
	}

	[Command]
	void Cmdcol(GameObject obj,Color col){
		obj.GetComponent<Renderer>().material.color = col;
	}



	void Update () {

		Move();
	}

	void Move(){
		icol=mycol;

		if(isServer){
			mycol = GetComponent<Renderer>().material.color;

		}

		if(!isServer){
			GetComponent<Renderer>().material.color = mycol;
		}
	}
