iOS Object-Oriented Swift Complex Data Structures Custom Initializers

How do I display "red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0" if i can't seem to interpolate in or out of struct?

I get an error when i interpolate inside the struct and outside the struct

i'm lost and can't seem to find out how else i'm suppose to have it display "red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0"

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.blue = blue
        self.green = green
        self.alpha = alpha
        self.description = description

let colorObject = RGBColor(red: 91.0, green: 191.0, blue: 131.0, alpha: 1.0,
                  description: "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
