js to C# converstion Problem

I am trying to convert a script from js to C# and it all works but one part and I am not sure how to fix this. The error I am getting is this :

Assets/Scripts/Cells.cs(14,21): error CS0119: Expression denotes a type', where a variable', value' or method group' was expected

The script is this:

 using UnityEngine;
 using System.Collections;
 
 public class Cells : MonoBehaviour {
 
 Transform[] Adjacents;
 Vector3 position;
 int weight;
 Color highLight;
 Color colorPlate;
 
 
 void  Start (){
     highLight = Color(1, 0, 0, 1);
     colorPlate = renderer.material.GetColor("_Color");
 }
 
 void  OnMouseEnter (){
     renderer.material.color = highLight;
 }
 
 void  OnMouseExit (){
     renderer.material.SetColor ("_Color", colorPlate);
 }
 }
