DynamicColor provides powerful methods to manipulate colours in an easy way in Swift (iOS/OSX/WatchOS/tvOS).

Firstly, DynamicColor provides useful initializers to create colors using hex strings or values:

let color = UIColor(hexString: "#3498db")
// equivalent to
// color = UIColor(hex: 0x3498db)

To be platform independent, the typealias DynamicColor can also be used:

let color = DynamicColor(hex: 0x3498db)
// On iOS, WatchOS or tvOS, equivalent to
// color = UIColor(hex: 0x3498db)
// On OSX, equivalent to
// color = NSColor(hex: 0x3498db)

These two create a new color by adjusting the lightness of the receiver. You have to use a value between 0 and 1.

let originalColor = UIColor(hexString: "#c0392b")

let lighterColor = originalColor.lighterColor()
// equivalent to
// lighterColor = originalColor.lightenColor(0.2)

let darkerColor = originalColor.darkerColor()
// equivalent to
// darkerColor = originalColor.darkenColor(0.2)

These will adjust the saturation of the color object, much like darkenColor and lightenColor adjusted the lightness. Again, you need to use a value between 0 and 1.

let originalColor = UIColor(hexString: "#c0392b")

let saturatedColor = originalColor.saturatedColor()
// equivalent to
// saturatedColor = originalColor.saturateColor(0.2)

let desaturatedColor = originalColor.desaturatedColor()
// equivalent to
// desaturatedColor = originalColor.desaturateColor(0.2)

let grayscaleColor = originalColor.grayscaledColor()

These adjust the hue value of the color in the same way like the others do. Again, it takes a value between 0 and 1 to update the value.

let originalColor = UIColor(hexString: "#c0392b")

let adjustHueColor = originalColor.adjustedHueColor(45 / 360)

let complementColor = originalColor.complementColor()

A tint is the mixture of a color with white and a shade is the mixture of a color with black. Again, it takes a value between 0 and 1 to update the value.

let originalColor = UIColor(hexString: "#c0392b")

let tintColor = originalColor.tintColor()
// equivalent to
// tintColor = originalColor.tintColor(amount: 0.2)

let shadeColor = originalColor.shadeColor()
// equivalent to
// shadeColor = originalColor.shadeColor(amount: 0.2)

This can invert the color object. The red, green, and blue values are inverted, while the opacity is left alone.

let originalColor = UIColor(hexString: "#c0392b")

let invertColor = originalColor.invertColor()

This can mix a given color with the receiver. It takes the average of each of the RGB components, optionally weighted by the given percentage (value between 0 and 1).

let originalColor = UIColor(hexString: "#c0392b")

let mixColor = originalColor.mixWithColor(UIColor.blueColor())
// equivalent to
// mixColor = originalColor.mixWithColor(UIColor.blueColor(), weight: 0.5)

DynamicColor also provides many another useful methods to manipulate the colors like hex strings, color components, etc. To go further, take a look at the example project.

Install CocoaPods if not already available:

$ [sudo] gem install cocoapods
$ pod setup

Go to the directory of your Xcode project, and Create and Edit your Podfile and add DynamicColor:

$ cd /path/to/MyProject
$ touch Podfile
$ edit Podfile
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

use_frameworks!
pod 'DynamicColor', '~> 2.4.0'

Install into your project:

$ pod install

Open your project in Xcode from the .xcworkspace file (not the usual project file):

$ open MyProject.xcworkspace

You can now import DynamicColor framework into your files.

Carthage is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate DynamicColor into your Xcode project using Carthage, specify it in your Cartfile file:

github "yannickl/DynamicColor" >= 2.4.0

You can use The Swift Package Manager to install DynamicColor by adding the proper description to your Package.swift file:

import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    targets: [],
    dependencies: [
        .Package(url: "https://github.com/yannickl/DynamicColor.git", versions: "2.4.0" ..< Version.max)
    ]
)

Note that the Swift Package Manager is still in early design and development, for more infomation checkout its GitHub Page

Download the project and copy the DynamicColor folder into your project to use it in.
