Hue IconYou can easily use hex colors with the init(hex:) convenience initializer on UIColor. It supports the following hex formats #ffffff, ffffff, #fff, fff

let white = UIColor(hex: "#ffffff")
let black = UIColor(hex: "#000000")
let red = UIColor(hex: "#ff0000")
let blue = UIColor(hex: "#0000ff")
let green = UIColor(hex: "#00ff00")
let yellow = UIColor(hex: "#ffff00")

Computed color properties

let white = UIColor(hex: "#ffffff")
let black = UIColor(hex: "#000000")

if white.isDarkColor {} // return false
if white.isBlackOrWhite {} // return true


.alpha is a sugar for colorWithAlphaComponent, internally it does the exact same thing, think of it as a lipstick for your implementation.

let colorWithAlpha = myColor.alpha(0.75)


You can easily create gradient layers using the gradient() method on arrays with UIColor. As an extra bonus, you can also add a transform closure if you want to modify the CAGradientLayer.

let gradient = [UIColor.blackColor(), UIColor.orangeColor()].gradient()

let secondGradient = [UIColor.blackColor(), UIColor.orangeColor()].gradient { gradient in
  gradient.locations = [0.25, 1.0]
  return gradient

Image colors

let image = UIImage(named: "My Image")
let (background, primary, secondary, detail) = image.colors()


You can get red, green, blue, and alpha components from any UIColor by using the (red|green|blue|alpha)Component property.

let myColor = UIColor(hex: "#ffafc2")
let myColorBlueComponent = myColor.blueComponent
let myColorGreenComponent = myColor.greenComponent
let myColorRedComponent = myColor.redComponent
let myColorAlphaComponent = myColor.alphaComponent


let red = UIColor.redColor()
let green = UIColor.greenColor()
let yellow = red.addRGB(green)

let desaturatedBlue = UIColor(hex: "#aaaacc")
let saturatedBlue = desaturatedBlue.addHue(0.0, saturation: 1.0, brightness: 0.0, alpha: 0.0)


Hex Example screenshot


This super simple example that displays a bunch of color schemes in a Carousel view.

It uses hex to set the color for the schemes. It leverages from .isDarkColor to make the text color readable in all scenarios.

The demo also features Spots for rendering the Carousel view.

Example code:

let color = UIColor(hex: "#3b5998")
backgroundColor = color
label.textColor = color.isDark
  ? UIColor.whiteColor()
  : UIColor.darkGrayColor()


Gradients Example screenshot

This examples shows how much fun you can have with combining CAGradientLayer with CABasicAnimation.

It uses .hex for getting the colors and .gradient() for transforming a collection of UIColor's into a CAGradientLayer.

The demo features Spots for rendering the list view and Fakery for generating random content strings.

Extract from the demo:

lazy var gradient: CAGradientLayer = [
  UIColor(hex: "#FD4340"),
  UIColor(hex: "#CE2BAE")
  ].gradient { gradient in
    gradient.speed = 0
    gradient.timeOffset = 0

    return gradient


Hue is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'Hue'

Hue is also available through Carthage. To install just write into your Cartfile:

github "hyperoslo/Hue"
