A small helper script for coloring the box collider in runtime in scene view and game view even if not selecting the gameobject with the collider.
the problem or another feature i want to add is when selecting in the enum the mode DrawOnBoth that it will draw in the scene view window in red and in the game view window in green.
Now when the mode is DrawOnBoth both windows scene view and game view are drawn in green color.

The below condition separates SceneView and GameView. If the above codes are not a problem, the answer is this.
DrawGizmosOnRunTime(SceneView.currentDrawingSceneView() ? Color.red : Color.green);
