Changing Camera Background Color With A Color Array Isn't Working

Questions & Answers
1

So I am trying to declare a color array by using this.

Color[] Colors = {new Color(84, 60, 39), new Color(167, 156, 135), new Color(138, 106, 71), new Color(202, 203, 199), new Color(187, 151, 142), new Color(188, 182, 178)};

It works just fine, there’s no error so I tried using the array to change my Camera Background color by doing this.

Main_Camera.backgroundColor = Colors[index];

The result is that the Main_Camera immediately change it’s color to white. I don’t know why.

This is the complete code if necessary:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using TMPro;

public class ChangingPicture : MonoBehaviour
{

    public Button NextButton;
    public Button BackButton;
    public Image ImageUI;
    public TMP_Text Title;
    public Camera Main_Camera;

    public Sprite[] Pictures;
    string[] Pictures_Text = {"Coffee", "Tea", "Thai Tea", "Milk", "Soda", "McFlurry"};
    Color[] Colors = {new Color(84, 60, 39), new Color(167, 156, 135), new Color(138, 106, 71), new Color(202, 203, 199), new Color(187, 151, 142), new Color(188, 182, 178)};

    int index, LowerLimit = 0, UpperLimit = 5;

    // Start is called before the first frame update
    void Start()
    {
        index = 0;
        
        UpdateAll(); 

        NextButton.onClick.AddListener(Forward);
        BackButton.onClick.AddListener(Backward);
    }

    // Update is called once per frame
    void Update()
    {
        //do nothing
    }
    

    void Forward() {
        if(index >= UpperLimit) {
            index = UpperLimit;
        } else {
            index++;
        }

        UpdateAll();
    }

    void Backward() {
        if(index == LowerLimit) {
            index = LowerLimit;
        } else {
            index--;
        }

        UpdateAll();
    }

    void UpdateAll() {
        ImageUI.sprite = Pictures[index];
        Title.text = Pictures_Text[index];
        Main_Camera.backgroundColor = Colors[index];

        Debug.Log(Colors[index]);
    }
}

I can’t say why your background is going white but you are missing a step. You have to set cam.clearflags first. The following code works as expected:

using UnityEngine;

public class Test4 : MonoBehaviour
{
    void Start()
    {
        Camera cam = Camera.main;
        cam.clearFlags = CameraClearFlags.SolidColor;
        cam.backgroundColor = Color.red;
    }
}
