access Xcode color picker 'Pencils' option programmatically - ios

Question

When I choose my button's background color in the storyboard, I can use a colorpicker widget. One of the tabs is called 'pencils'.
This tab shows a picture of coloring pencils lined up. One pencil has the color 'mercury'.
Is there a way to access this predefined color through the UIColor object?
e.g.
let myColor = UIColor(pencils: "mercury")

Answer 1

You could access Mercury color in code this way:
let myColor = Color
Click on the white square, then click on others, finally you could select Mercury color in the pencil tab.

I wanted to do the same thing, so I created a custom class. Hope this saves someone else some time :)
To access, call PencilColors.instance...
import Foundation
import UIKit
class PencilColors {
static let instance = PencilColors()
let pencilColors: [(color: UIColor, name: String, type: Int)] = [
//instead of creating an enum in each project:
//type 0 -> black and white
//type 1 -> dark colors
//type 2 -> medium colors
//type 3 -> light colors
(color: .black, name: "Black", type: 0),
