Better Memory Allocation For Random Colors Just Like Fun Facts Model?

As we stored the property of factModel as an instance of FactModel() outside of the showFunFact() function to optimize memory usage as Pasan mentioned in the fact model video, should we not do the same for the color model? Like this:

@IBOutlet weak var funFactButton: UIButton!
let randomColor = ColorModel()

@IBAction func showFunFact() {
    view.backgroundColor = randomColor.getRandomColor()
    funFactButton.tintColor = view.backgroundColor
    funFactLabel.text = factModel.getRandomFact()
}

Is there an any advantage to write the code as Pasan wrote, which is:

@IBOutlet weak var funFactButton: UIButton!

@IBAction func showFunFact() {
    let randomColor = ColorModel().getRandomColor()
    view.backgroundColor = randomColor
    funFactButton.tintColor = randomColor
    funFactLabel.text = factModel.getRandomFact()
}
