    let alpha: Double

    let description: String

    // Add your code below

        self.alpha = 1.0

        self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"

Hi Kapil!

In this task, you are not supposed to hardcode the numbers. You are using correct numbers, however, you should pass them as parameters to an instance, not hardcode them.

In init() method, add 4 parameters (red, blue, green and alpha) and add them to appropriate line (for example, if you have parameter "red", you will add it to "self.red")
