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

self.green = 191.0
self.blue = 131.0
self.alpha = 1.0

Front End Web Development Techdegree Graduate 84,738 Points1) The word "custom" isn't a special keyword in swift. Treehouse is just telling you to write your own initializer method, as structs come with one by default behind the scenes.
2) We don't need to pass in a description parameter. The description is composed from the other values, it's not passed in separately.
3) We want to set the values on self from the parameters that get passed into the init method. Right now you're hard-coding in the numbers 86.0, 191.0, etc. These were just examples of some numbers that might get passed in, but they could be any numbers.
Let me know if you're still having trouble.
