## Requirements



- iOS 11.0+ / Mac OS X 10.11+ / tvOS 11.0+ / watchOS 4.0+

- Xcode 10.2+

- Swift 5.0+



## Usage



#### Creation (Hex String)



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



```swift

let color = UIColor(hexString: "#3498db")

// equivalent to

// color = UIColor(hex: 0x3498db)

```



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



```swift

let color = DynamicColor(hex: 0x3498db)

// On iOS, WatchOS or tvOS, equivalent to

// color = UIColor(hex: 0x3498db)

// On OSX, equivalent to

// color = NSColor(hex: 0x3498db)

```



You can also retrieve the RGBA value and components very easily using multiple methods like `toHexString`, `toHex`, `toRGBA`, etc.



##### SwiftUI



From the v5, DynamicColor also support basic methods to create and manipulate colors with SwiftUI.



```swift

let color = Color(hex: 0x3498db)

```



#### Darken & Lighten



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





  lighten and darken color




```swift

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



let lighterColor = originalColor.lighter()

// equivalent to

// lighterColor = originalColor.lighter(amount: 0.2)



let darkerColor = originalColor.darkened()

// equivalent to

// darkerColor = originalColor.darkened(amount: 0.2)

```



#### Saturate, Desaturate & Grayscale



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





  saturate, desaturate and grayscale color




```swift

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



let saturatedColor = originalColor.saturated()

// equivalent to

// saturatedColor = originalColor.saturated(amount: 0.2)



let desaturatedColor = originalColor.desaturated()

// equivalent to

// desaturatedColor = originalColor.desaturated(amount: 0.2)



// equivalent to

// let grayscaledColor = originalColor.grayscaled(mode: .luminance)

let grayscaledColor = originalColor.grayscaled()



let grayscaledColorLuminance = originalColor.grayscaled(mode: .luminance)

let grayscaledColorLightness = originalColor.grayscaled(mode: .lightness)

let grayscaledColorAverage = originalColor.grayscaled(mode: .average)

let grayscaledColorValue = originalColor.grayscaled(mode: .value)

```



#### Adjust-hue & Complement



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.





  ajusted-hue and complement color




```swift

let originalColor = DynamicColor(hex: 0xc0392b)



// Hue values are in degrees

let adjustHueColor = originalColor.adjustedHue(amount: 45)



let complementedColor = originalColor.complemented()

````



#### Tint & Shade



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.





tint and shade color




```swift

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



let tintedColor = originalColor.tinted()

// equivalent to

// tintedColor = originalColor.tinted(amount: 0.2)



let shadedColor = originalColor.shaded()

// equivalent to

// shadedColor = originalColor.shaded(amount: 0.2)

```



#### Invert



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





  invert color




```swift

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



let invertedColor = originalColor.inverted()

```



#### Mix



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).





mix color




```swift

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



let mixedColor = originalColor.mixed(withColor: .blue)

// equivalent to

// mixedColor = originalColor.mixed(withColor: .blue, weight: 0.5)

// or

// mixedColor = originalColor.mixed(withColor: .blue, weight: 0.5, inColorSpace: .rgb)

```



#### Gradients



**DynamicColor** provides an useful object to work with gradients: **DynamicGradient**. It'll allow you to pick color from gradients, or to build a palette using different color spaces (.e.g.: *RGB*, *HSL*, *HSB*, *Cie L\*a\*b\**).



Let's define our reference colors and the gradient object:

```swift

let blue   = UIColor(hexString: "#3498db")

let red    = UIColor(hexString: "#e74c3c")

let yellow = UIColor(hexString: "#f1c40f")



let gradient = DynamicGradient(colors: [blue, red, yellow])

// equivalent to

// let gradient = [blue, red, yellow].gradient

```



##### RGB



Let's build the RGB palette (the default color space) with 8 colors:





RGB gradient




```swift

let rgbPalette = gradient.colorPalette(amount: 8)

```



##### HSL



Now if you want to change the gradient color space to have a different effect, just write the following lines:





HSL gradient




```swift

let hslPalette = gradient.colorPalette(amount: 8, inColorSpace: .hsl)

```



##### Cie L\*a\*b\*



Or if you prefer to work directly with array of colors, you can:





Cie L*a*b* gradient




```swift

let labPalette = [blue, red, yellow].gradient.colorPalette(amount: 8, inColorSpace: .lab)

```



#### And many more...



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



## Installation



#### CocoaPods



Install CocoaPods if not already available:



``` bash

$ [sudo] gem install cocoapods

$ pod setup

```

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



``` bash

$ cd /path/to/MyProject

$ touch Podfile

$ edit Podfile

source 'https://github.com/CocoaPods/Specs.git'

platform :ios, '8.0'



use_frameworks!

pod 'DynamicColor', '~> 5.0.0'

```



Install into your project:



``` bash

$ pod install

```



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



``` bash

$ open MyProject.xcworkspace

```



You can now `import DynamicColor` framework into your files.



#### Carthage



[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.



You can install Carthage with [Homebrew](http://brew.sh/) using the following command:



```bash

$ brew update

$ brew install carthage

```



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



```ogdl

github "yannickl/DynamicColor" >= 5.0.0

```



#### Swift Package Manager

You can use [The Swift Package Manager](https://swift.org/package-manager) to install `DynamicColor` by adding the proper description to your `Package.swift` file:

```swift

import PackageDescription



let package = Package(

    name: "YOUR_PROJECT_NAME",

    targets: [],

    dependencies: [

        .package(url: "https://github.com/yannickl/DynamicColor.git", from: "5.0.0")

    ]

)

```



Note that the [Swift Package Manager](https://swift.org/package-manager) is still in early design and development, for more information checkout its [GitHub Page](https://github.com/apple/swift-package-manager).



#### Manually



[Download](https://github.com/YannickL/DynamicColor/archive/master.zip) the project and copy the `DynamicColor` folder into your project to use it in.
