🎨 A tiny (Kotlin) library for generating attractive colors

Inspired by David Merfield's randomColor.js. You can use the library to generate attractive random colors on Android apps.

This project comes with a sample app which demonstrates some of the functionality:

The library is hosted on JitPack

1. Add it in your root build.gradle at the end of repositories:

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

2. Add the dependency

dependencies {
    implementation 'com.github.brian-norman:RandomKolor:1.0'
}

• hue – Controls the hue of the generated color. You can pass in a color: Color.RED, Color.ORANGE, Color.YELLOW, Color.Green, Color.BLUE, Color.Purple, Color.PINK and Color.MONOCHROME are currently supported.
• luminosity – Controls the luminosity of the generated color. Library supports: Luminosity.RANDOM, Luminosity.BRIGHT, Luminosity.LIGHT, Luminosity.DARK
• count – An integer which specifies the number of colors to generate.

fun randomColor(hue: Hue = RandomHue, luminosity: Luminosity = Luminosity.RANDOM, format: Format = Format.RGB): String

fun randomColors(count: Int, hue: Hue = RandomHue, luminosity: Luminosity = Luminosity.RANDOM, format: Format = Format.RGB): List<String>

// Generate an attractive color (RGB) randomly
val rgbString = RandomKolor().randomColor()

// Generate a light blue (HEX)
val rgbString = RandomKolor().randomColor(hue = ColorHue(BLUE), luminosity = Luminosity.LIGHT, format = Format.HEX)

// Generate three light oranges (HSL)
val rgbStrings = RandomKolor().randomColors(count = 3, hue = ColorHue(ORANGE), luminosity = Luminosity.LIGHT, format = Format.HSL)

• David Merfield's original library
• Wei Wang's swift port RandomColorSwift

• Add alpha to RGB
