See what object I hit in raycast

I am trying to see what object I hit with the raycast and then change the objects color. Here is my code. I don't know what exactly I am doing wrong. I am getting this error "Assets/Scripts/Shoot.cs(16,56): error CS0120: An object reference is required to access non-static member `UnityEngine.RaycastHit.collider'" Thanks in advance! ~Brady

 using UnityEngine;

using System.Collections;

public class Shoot : MonoBehaviour {

private GameObject objectHit;

 void Update() {

 CheckIfCollide();

     }

 

public void CheckIfCollide() {

 if(Input.GetKeyDown(KeyCode.LeftShift)) {

         Vector3 fwd = transform.TransformDirection(Vector3.forward);

         if (Physics.Raycast(transform.position, Camera.main.transform.forward, 10)) {

             Debug.Log("There is something in front of the object!");

             Debug.DrawRay(transform.position, Camera.main.transform.forward, Color.blue, 10);

             objectHit = RaycastHit.collider;

             objectHit.renderer.material.color = Color.red;    

         }

             

         else {

             Debug.Log("There Is nothing in front of the object!"); 

             Debug.DrawRay(transform.position, Camera.main.transform.forward, Color.red, 10);

         }

     }

 }

}
