You will have to add an initializer to your struct. Naturally, structs will already have an initializer (If you created an instance of this struct it would give you something like this, given what you already have:

RGBColor(red: #redValue, green: #greenValue, blue: #blueValue, alpha: #alphaValue, description: #descriptionValue)

What you will need to do is create your own initializer that allows you to use the values (redValue, greenValue, blueVlaue, alphaValue) to create a custom string description.

Not trying to give the final answer but you will need to pass in the parameters you need to set the color values and alpha value so that you can create the description string possibly using String interpolation. All the best!
