Diffrent colors after restart scene (unwittingly )

So I made simple game where you can restart scene after lose. I used SceneManager.LoadScene("Minigame", LoadSceneMode.Single);
After restar I have diffrent colors: Before and After
Do you know why is this happening and how to fix it? I don’t have any color modifications in my code.
