Change color from script

I'm making an app for school with a question and 3 answers. 1 answer is good and the other 2 are false. Now i want to change the color of the button to green if it's good and to red if it's false. I want to do this from the inspector, but i don't know how to apply this to the button.

This is my script.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class LevelManager : MonoBehaviour {
     // answers
     public string Question;
     public string answer1;
     public string answer2;
     public string answer3;
 
     // colors
     public Color FalseAnswerColor;
     public Color GoodAnswerColor;
  
     // get the text elements
     public UnityEngine.UI.Text Questiontext;
     public UnityEngine.UI.Text Answertext1;
     public UnityEngine.UI.Text Answertext2;
     public UnityEngine.UI.Text Answertext3;
 
     // get the button elements
     public UnityEngine.UI.Button AnswerButton1;
     public UnityEngine.UI.Button AnswerButton2;
     public UnityEngine.UI.Button AnswerButton3;
 
     void Start ()
     {
         Questiontext.text = Question;
         Answertext1.text = answer1;
         Answertext2.text = answer2;
         Answertext3.text = answer3;
     }
 
     /*
     // The answer is true
     public void RightAnswer ()
     {
         // reward animation
         // Create the reward animation and implement it
         // change the color to green
 
     }
     */
 
     // The Answer is false
     public void FalseAnswer ()
     {
         // change the color the red
 
     }
 }
