Shorthand to create UIColor from Int values 0-255

Color.swift

import Foundation
import UIKit

extension UIColor {
    static func RGBA(r:Int, _ g: Int, _ b:Int, _ a:Int) -> UIColor {
        return UIColor(red: CGFloat(r)/255.0, green: CGFloat(g)/255.0, blue: CGFloat(b)/255.0, alpha: CGFloat(a)/100.0)
    }
    static func RGB(r:Int, _ g: Int, _ b:Int) -> UIColor {
        return UIColor.RGBA(r, g, b, 100)
    }
