Palletize

Tools for collections of colors.

Insert a library of color swatches, then query individual or batches of swatches based on visual attributes. Consumes a hex string for each swatch, then calculates and attaches additional data points for rgba, hsla, and luminance.

Installation

Install the palletize package

npm i palletize

Usage

  1. Prepare your library of swatches. Each swatch must have a unique id string and hex string properties:
[
  {
    "id": "naturally-white",
    "hex": "#fffffd",
  },
  {
    "id": "egyptian-cotton",
    "hex": "#fdfdfb",
  },
  {
    "id": "cotton",
    "hex": "#fffef9",
  },
  ...
]
  1. Initialize a palette using the library:
const Palletize = require('palletize')
const Palette = Palletize(require('./natural-paint-co.json'))
  1. Query swatches using the fetcher methods (detailed below)
const color = Palette.id('cotton')
console.log(color)

API

id(id)

Query a single swatch by it's id

random(n = 1)

Query randomized swatches from the whole library

luminance(min, max, n = 1)

Query randomized swatches within a luminance range

hue(theta, range, n = 1)

Query randomized swatches within a range on the hue wheel
theta: Degrees around the hue wheel 0:red -> 120:green -> 240:blue
range: Degrees in either direction on the wheel to include in results

saturation(min, max, n = 1)

Query randomized swatches within a saturation range

lightness(min, max, n = 1)

Query randomized swatches within a lightness range

hsl(hue, saturation, lightness, n = 1)

Query randomized swatches that match the HSL ranges
hue: [theta, range]
saturation: [min, max]
lightness: [min, max]

Exclude

All randomized methods can provide an exclude array as the final argument; these items are excluded from the selection process:

const background = Palette.id('cotton')
const colors = Palette.random(10, [background]) // `Cotton` swatch excluded from selection pool

Examples

Palette.id('black-robin')


Palette.random(10)


Palette.luminance(0, 0.2, 10)


Palette.luminance(0.6, 1, 10)


Palette.hue(0, 15, 10)


Palette.hue(120, 30, 10)


Palette.hue(200, 30, 10)


Palette.saturation(0.5, 1, 10)


Palette.saturation(0, 0.1, 10)


Palette.lightness(0, 0.33, 10)


Palette.lightness(0.8, 1, 10)


Palette.hsl([0, 45], [0.5, 1], [0.7, 1], 10)


Palette.hsl([150, 35], [0, 0.33], [0, 0.5], 10)


Palette.hsl(undefined, [0.5, 1], [0.5, 1], 10)
