change view colour on tap then back to original colour

Question

I am trying to use UITapGestureRecognizer to change a UIView color when the view is tapped, then back to the original white color when space outside the UIView is tapped. I can get the UIView to change colors but I cannot get it to change back to white color.

  // viewDidLoad
let tapGestureRegonizer = UITapGestureRecognizer(target: self, action: 
#selector(mortgagePenaltyVC.viewCellTapped(recognizer:)))
    tapGestureRegonizer.numberOfTapsRequired = 1
    mortgageLenerViewCell.addGestureRecognizer(tapGestureRegonizer)

@objc func viewCellTapped (recognizer: UITapGestureRecognizer){
    print("label Tapped")


    mortgageLenerViewCell.backgroundColor = UIColor.lightGray



    }

I think you can use touchesBegan method to get the touch outside of view like below

This code works for me...

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let touch = touches.first
    guard let location = touch?.location(in: mortgageLenerViewCell) else { return }
    if !labelToClick.frame.contains(location) {
        print("Tapped outside the view")
        mortgageLenerViewCell.backgroundColor = UIColor.white
    }else {
        print("Tapped inside the view")
        mortgageLenerViewCell.backgroundColor = UIColor.lightGray
    }
}

here labelToClick is the label on which you want to click & mortgageLenerViewCell is the superview of labelToClick

Feel free to ask for any query...

Thank you.
