DynamicColor provides powerful methods to manipulate colors in an easy way in Swift and SwiftUI.
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)
You can also retrieve the RGBA value and components very easily using multiple methods like
From the v5, DynamicColor also support basic methods to create and manipulate colors with SwiftUI.
let color = Color(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 = 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)
These will adjust the saturation of the color object, much like
lighter adjusted the lightness. Again, you need to use a value between 0 and 1.
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)
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 = DynamicColor(hex: 0xc0392b) // Hue values are in degrees let adjustHueColor = originalColor.adjustedHue(amount: 45) let complementedColor = originalColor.complemented()
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 = 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)
This can invert the color object. The red, green, and blue values are inverted, while the opacity is left alone.
let originalColor = DynamicColor(hexString: "#c0392b") let invertedColor = originalColor.inverted()
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 = 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)
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:
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
Let's build the RGB palette (the default color space) with 8 colors:
let rgbPalette = gradient.colorPalette(amount: 8)
Now if you want to change the gradient color space to have a different effect, just write the following lines:
let hslPalette = gradient.colorPalette(amount: 8, inColorSpace: .hsl)
Or if you prefer to work directly with array of colors, you can:
let labPalette = [blue, red, yellow].gradient.colorPalette(amount: 8, inColorSpace: .lab)
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.
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', '~> 5.0.0'
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
DynamicColor into your Xcode project using Carthage, specify it in your
github "yannickl/DynamicColor" >= 5.0.0
You can use The Swift Package Manager to install
DynamicColor by adding the proper description to your
import PackageDescription let package = Package( name: "YOUR_PROJECT_NAME", targets: , dependencies: [ .package(url: "https://github.com/yannickl/DynamicColor.git", from: "5.0.0") ] )
Download the project and copy the
DynamicColor folder into your project to use it in.
