Lightweight framework for generating visually aesthetic color-schemes in Swift
Requirements
- UIKit
Features
What can Lorikeet do for you
- Calculate visual color difference (wikipedia)
- Algorithms:
- CIE76
- CIE94
- CIE2000
- Algorithms:
- Generate color schemes
github “valdirunars/Lorikeet”
In you Podfile
pod ‘Lorikeet’
Copy the ./Lorikeet folder 😁🗂
How to Use
Basic Usage
let red: UIColor = .red
let label = UILabel()
label.backgroundColor = red
// Assign a maximum contrasting color as foreground color
label.textColor = red.lkt.complimentaryColor
// Visual color difference
let distance: Float = red.distance(to: .blue, algorithm: .cie2000)
// Generate color scheme
red.lkt.generateColorScheme(numberOfColors: 40) { colors in
print(colors)
}
Lorikeet’s Algorithm enum has two cases for advanced usage:
.advancedCIE94(l: Float, c: Float, h: Float, k1: Float, k2: Float)
.advancedCIE2000(l: Float, c: Float, h: Float)
Example:
let l: Float = 0.8
let c: Float = 0.9
let h: Float = 1.0
red.lkt.generateColorScheme(numberOfColors: 40,
using: .advancedCIE2000(l: l, c: c, h: h)) { colors in
print(colors)
}
let range = HSVRange(hueRange: (0, 1),
saturationRange: (0.5, 0.5),
brightnessRange: (0.95, 0.95))
color.lkt.generateColorScheme(numberOfColors: 15,
withRange: range,
using: .cie2000) {
colors in
}
Making text readable using random colors:
let label = UILabel(frame: frame)
self.view.backgroundColor = UIColor(hue: 180/360.0,
saturation: 0.5,
brightness: 0.6,
alpha: 1)
label.backgroundColor = self.view
.backgroundColor!
.lkt
.generateRandomMatchingColor()
label.textColor = label.backgroundColor!
.lkt
.complimentaryColor
Generating colors:
let color: UIColor = UIColor(red: 245/255.0, green: 110/255.0, blue: 100/255.0, alpha: 1)
color.lkt.generateColorScheme(numberOfColors: 10)
