Monogame - Changing background colour error

I'm building a 2D platformer and I want to have different colour backgrounds for each level. I've made an object that when collided with, it places the character onto the next level by changing the player.Position, like so...

protected override void Update(GameTime gameTime){

    if (player.Bounds.Intersects(teleportObj.Bounds))
    {
        GraphicsDevice.Clear(Color.SlateGray); // fails to change bg color
        player.Position = new Vector2(172, 0); // successfully changes character position
        MediaPlayer.Play(dungeonSong);  // successfully plays new song
        MediaPlayer.IsRepeating = true;  // successfully repeats new song
    }
}

I have already set a background for the first level to begin with in the Game1's Draw() function like this: 

GraphicsDevice.Clear(Color.CornflowerBlue);

But when my player collides with teleportObj, the background color doesn't change.

GraphicsDevice.Clear(Color.SlateGray); is used in Draw function. Try creating new Color variable, and change that variable in Update method, and when using GraphicsDevice.Clear(name of the variable);, use it in Draw function.

Code for that would look like this:

Color backgroundColor = Color.CornflowerBlue;
protected override void Update(GameTime gameTime)
{    
    if (player.Bounds.Intersects(teleportObj.Bounds))
    {
        backgroundColor = Color.SlateGray;
        player.Position = new Vector2(172, 0); 
        MediaPlayer.Play(dungeonSong);
        MediaPlayer.IsRepeating = true;
    }
    else backgroundColor = Color.CornflowerBlue; 
}

protected override void Draw(SpriteBatch spriteBatch)
{    
    GraphicsDevice.Clear(backgroundColor);
    *draw other stuff*
}
