Canvas Error - Everything tinted blue

@Brainrush1 Howdy! Not sure if you're still having this issue, but the same thing just happened to me. Somewhere in a script, I had done this:

 void SetColor(Color newColor)
 {
     canvasElement.material.color = newColor;
 ...
 }

The problem with this is twofold:

1. Canvas elements have a default shared material called "none" (yes, "none" is an actual material, not the absence of one). When you modify canvasElement.material.color you're changing the "none" material's color, meaning you're changing the color of every canvas element with the "none" material.

2. This change persists even after you've quit out of the game, meaning it doesn't automatically reset like most other in-game changes do.

To fix this,

1. Comment out or Remove any code that's similar to the problem code above (tip: Command/Control + F for "material.color").

2. put this C# script on an empty gameObject in the scene:

    using UnityEngine;
    using UnityEngine.UI;
    public class MaterialFixer : MonoBehaviour
     {
       // When the game starts,
       void Awake()
       {
         // Add an Image component to this GameObject
         Image canvasElement = gameObject.AddComponent<Image>();
         // and change the Image's material, shared between all canvas elements, back to white.
         canvasElement.material.color = Color.white;
       }
     }
   
   

3. Hit the Play button. The color of all Canvas elements should return to normal and stay that way. You can now safely remove the script.

Let me know if this helps, or if you have any other issues. Cheers!
