Question Null texture passed to GUI.Draw Texture.

I am trying to embed a texture into a custom editor window, when running the script it produces the following error:

ignore the unity forum emojis lol.

The texture is just a normal texture, works when using it on a canvas image etc.

the texture is located in the Editor Default Resources folder, that's why I've tried using the EditorGUIUtility.Load function.

Is there something I am missing?

Code (CSharp):

1. public class WindPainter : EditorWindow
2. {
3.     // tried setting the texture manually by picking it.
4.     // public Texture ColorWheel;
5.     Color color;
6.     public float BrushSize = 100;
7.     public float WindDirection = 1;
8.     public float Intensity = 50;
9.  
10.     [MenuItem("Tools/Wind Painter")]
11.     public static void ShowWindow()
12.     {
13.         GetWindow(typeof(WindPainter));
14.     }
15.  
16.     private void OnGUI()
17.     {
18.         GUILayout.Label("Wind Brush", EditorStyles.boldLabel);
19.         //tried obtaining it this way as well.
20.         Texture ColorWheel = (Texture)EditorGUIUtility.Load("ColorWheel");
21.  
22.         GUI.DrawTexture(new Rect(10, 10, 200, 200), ColorWheel, ScaleMode.ScaleToFit, true, 10.0F);
23.  
24.         EditorGUILayout.Space();
25.         EditorGUILayout.Space();
26.         EditorGUILayout.Space();
27.         EditorGUILayout.Space();
28.  
29.         WindDirection = EditorGUILayout.Slider("Wind Direction", WindDirection, 1f, 360f);
30.  
31.         Intensity = EditorGUILayout.Slider("Intensity", Intensity, 0, 100);
32.  
33.         BrushSize = EditorGUILayout.Slider("Brush Size", BrushSize, 50f, 500f);
34.     }
35. }

Edit: I did a debug check to see if either of the methods were even loading the texture at all and it came back false for both, even though I can see the texture in the inspector.
