Put this code in your viewDidLoad method and see if it is what you are looking for

    self.view.backgroundColor = UIColor.blueColor()
    UIView.animateWithDuration(1.0, delay: 1.0, options: nil, animations: { () -> Void in
        self.view.backgroundColor = UIColor.greenColor()
    }, completion: nil)

If this is what you are looking for do something like

    if (score < 100){
        enemy.runAction(SKAction.moveTo(mainBall.position, duration:3))  
    }
    else if (score >= 100 && score < 200){
        enemy.runAction(SKAction.moveTo(mainBall.position, duration:2.5))
        UIView.animateWithDuration(0.5, animations: { () -> Void in
           self.backgroundColor = SKColor.purpleColor()
       })
    }
    else if (score >= 200 && score < 300){
        enemy.runAction(SKAction.moveTo(mainBall.position, duration:2))
         UIView.animateWithDuration(0.5, animations: { () -> Void in
           self.backgroundColor = SKColor.greenColor()
    })
    }`
