About

Möbius is a color palette generation tool designed for developers and designers who need quick, consistent, and attractive color schemes. It supports a wide variety of palette types and exports color data in multiple formats — RGB, HSL, LAB, CMYK, and more - making it ideal for both web design and data visualization.

Features

  • Generate palettes using:
    • Interpolation
    • Luminance shifts
    • Monochromatic, Complementary, Analogous, Triadic, Tetradic, etc.
  • Output in multiple color spaces: RGB, HSL, LCH, CMYK, etc.
  • Randomized or lightness-corrected options
  • Diverging palette support
  • TypeScript-friendly API

Demo

You can check out a working CodePen where you can adjust settings and colors here, or the website moebius.wtf.

Install

npm i -S @phun-ky/moebius

Full API-reference

You can find the full API documentation here.

Usage

Import and run the required function:

import Moebius from '@phun-ky/moebius';

const { MoebiusColor, MoebiusPalettes } = await Moebius();

const palette = new MoebiusPalettes({
  baseColor: new MoebiusColor('#1e90ff')
});

console.log(palette.colors.interpolate); // ['#1e90ff', '#3298d8', ...]

Creating palettes

The main feature is the ability to create palettes with a given primary color and a secondary color (used for diverging palettes). You can also give the color to diverge to/from.

Default options

const defaultOptions = {
  diverging: false,
  bezier: false,
  randomOffset: false,
  correctLightness: false,
  noDuplicates: true,
  colorScaleMode: 'lch',
  reverseDirection: false,
  divergentColor: '#f5f5f5'
};

You initiate MoebiusPalette like this:

import Moebius from '@phun-ky/moebius';

const { MoebiusPalette, MoebiusColor } = await Moebius();

const palettes = new MoebiusPalettes({
  baseColor: new MoebiusColor('#003f5c'),
  secondaryColor: new MoebiusColor('#ff9900'),
  ...options
});

And then you can enjoy your palettes!

Get color objects

import Moebius from '@phun-ky/moebius';

const { MoebiusColor } = await Moebius();

//
const color = new MoebiusColor('#003f5c');

console.log(color.hsl); // hsl(199, 100%, 18%);

This will make available a color object with all of the colors readily converted and ready to use. This is an example output of the color object:

{
  "color": "#003f5c",
  "name": "Maniac Mansion",
  "hex": "#003f5c",
  "rgb": "rgb(0, 63, 92)",
  "hsl": {
    "h": 199,
    "s": 100,
    "l": 18
  },
  "hwb": {
    "h": 0.45,
    "w": 0,
    "b": 0.64
  },
  "hsv": {
    "h": 198.91,
    "s": 1,
    "v": 0.36
  },
  "lab": {
    "l": 24.72,
    "a": -5.95,
    "b": -22.26
  },
  "xyz": {
    "x": 0.37,
    "y": 0.43,
    "z": 0.38
  },
  "lch": {
    "l": 24.72,
    "c": 23.04,
    "h": 255.03
  },
  "oklch": {
    "l": 0.35,
    "c": 0.08,
    "h": 236.65
  },
  "hsi": {
    "h": 197.96,
    "s": 1,
    "i": 0.2
  },
  "oklab": {
    "l": 0.35,
    "a": -0.04,
    "b": -0.06
  },
  "cmyk": {
    "c": 100,
    "m": 0,
    "y": 32,
    "k": 64
  }
}

toString

For the non-CSS units, the color object also exposes a toString method pr unit:

const color = new MoebiusColor('#003f5c');

console.log(color.hsl.toString()); // "199, 100, 18"

toObject

The color object exposes a toObject method, that allows to objectify from any color unit given to either a color object for the hsl units, or default rgb:

const color = new MoebiusColor('#003f5c');

console.log(color.toObject('hsl')); // "199, 100, 18"
console.log(color.toObject(); // "0, 63, 92"

toFloat

The color object exposes a toFloat method, that allows to objectify to float values, as in 0-1 instead of 0-255/0-100 from any color unit given to either a color object for the hsl units, or default rgb:

const color = new MoebiusColor('#003f5c');

console.log(color.toFloat('hsl')); // "199, 1, 0.18"
console.log(color.toFloat(); // "0, 0.25, 0.36"

p.s. Ukraine is still under brutal Russian invasion. A lot of Ukrainian people are hurt, without shelter and need help. You can help in various ways, for instance, directly helping refugees, spreading awareness, putting pressure on your local government or companies. You can also support Ukraine by donating e.g. to Red Cross, Ukraine humanitarian organisation or donate Ambulances for Ukraine.
