Can someone help me discover my mistake?

Thank you!

structs.swift 
struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

    init(red: Double, green: Double, blue: Double, alpha: Double) {
    self.red = red
    self.green = green
    self.blue = blue
    self.alpha = alpha
    self.description("red:\(red), green:\(green), blue:\(blue), alpha:\(alpha)")
    }
}

let color = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)

Great, except for one line:

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

description is not a function. It's a String variable, and the initializer needs to set it to a String. Also, the editor is very picky sometimes, and it wants a space between the text and the String interpolation: red: () rather than red:()
