What's wrong with the code?

Thought this was right, but not understanding why not. Thanks in advance!

colors.swift 
class ViewController: UIViewController {

    let blueColor = UIColor(red: 0/255.0, green: 0/255.0, blue: 255/255.0, alpha: 1.0)
    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        // Dispose of any resources that can be recreated
    }
}

In your color assignment you only need to pass in one value per property. Take a look at my blueColor:

  let blueColor = UIColor(red: 0, green: 0, blue: 255.0, alpha: 1.0)
