Cannot seem to figure this one out. It keeps saying use proper string interpolation to finish it.

Any help would be appreciated

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 = 86.0
        self.green = 191.0
        self.blue = 131.0
        self.alpha = 1.0
        self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
