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

    }
}
  1. Get a reference to the button you are changing. (Either thru the click event or by passing it to the method as a parameter somehow)
  2. Set the color of the button. Unity uses color blocks for buttons so that we can have pressed color, disabled color, etc.

Psuedocode:

ColorBlock cb = button.colors;

If (answer == wrong)
 cb.normalColor = FalseAnswercolor
else
 cb.normalcolor = goodanswercolor

 b.colors = cb; (assign the color block to the button)
