Color palette generator

A small, lightweight utility helper to generate color palettes based on a given input color.

Uses the theory explained in this video, which is to generate a base palette as a set of colors around the given base color by shifting its hue increasingly, then creates additional lighter and darker palettes by manipulating the base palette colors saturation and brightness.

Demo

Installation

npm

npm i @martinlaxenaire/color-palette-generator

yarn

yarn add @martinlaxenaire/color-palette-generator

Or use any other package manager.

Example

Creating colors

import { ColorModel } from '@martinlaxenaire/color-palette-generator'

const redColor = new ColorModel('#ff0000')
const randomColor = new ColorModel()
const greenColor = new ColorModel('#29ab63')

const brighterGreenColor = greenColor.clone().saturateHsv(10).brighten(10)

Creating palette generators

import { ColorModel, ColorPaletteGenerator } from '@martinlaxenaire/color-palette-generator'

// create a palette generator from a random color
const palette = new ColorPaletteGenerator()

const greenColor = new ColorModel('#29ab63')

// create another palette generator from a green color
const paletteFromColor = new ColorPaletteGenerator({
  precision: 6,
  baseColor: greenColor, // we could also pass 'greenColor.hex' hexadecimal representation
})

Getting random palettes

A random palette just picks colors randomly from the color palette generator.

import { ColorModel, ColorPaletteGenerator } from '@martinlaxenaire/color-palette-generator'

const greenColor = new ColorModel('#29ab63')

// create a palette from a green color
const paletteFromColor = new ColorPaletteGenerator({
  precision: 6,
  baseColor: greenColor, // we could also pass 'greenColor.hex' hexadecimal representation
})

// get a random palette of 4 colors based on 'paletteFromColor'
const randomPaletteFromColor = paletteFromColor.getRandomPalette()

Getting distributed palettes

A distributed palette picks colors based on their brightness/value. It picks half its colors on a medium brightness range (between 37.5 and 87.5), a quarter with low brightness (under 37.5) and the last quarter with high brightness (over 87.5).

import { ColorPaletteGenerator } from '@martinlaxenaire/color-palette-generator'

// create a palette from a random color
const palette = new ColorPaletteGenerator()

// get a distributed palette of 6 colors based on 'palette'
const distributedPalette = palette.getDistributedPalette({
  length: 6,
})

// get a distributed palette based on 'palette', excluding colors too dark or too light
const anotherDistributedPalette = palette.getDistributedPalette({
  minBrightness: 10,
  maxBrightness: 90,
})
