    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

    // Add your code below
    init(red: Double, green: Double, blue: Double, alpha: Double) {
        self.red = 86.0
        self.green = 131.0
        self.blue = 131.0
        self.alpha = 1.0
        self.description = ("red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0")

You've used specific RGB values in your init. Try this instead:

struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

    // Add your code below
    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)"
    }

}

var myColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
