@suaveplan/colours - Universal colour manipulation: parsing, conversion, analysis, mixing, blending, and palette generation

Universal colour manipulation library: parsing, conversion, analysis, mixing, blending, and palette generation. Parses hex (3/4/6/8 digit), CSS rgb(), hsl(), lab(), lch(), oklab(), oklch(), named colours, and plain objects. Converts between RGB, HSL, HSV, LAB, LCH, OKLAB, OKLCH, XYZ, and CMYK. Supports manipulation (lighten, darken, saturate, desaturate, rotate, alpha, fade, opaquer, negate, grayscale, mix), analysis (luminance, perceived brightness, contrast ratio, distance), and factories (random colours, temperature-based black-body curves, blend modes, gradient steps, harmonious palettes).

Quick Start

import { Colour } from "@suaveplan/colours";

const c = new Colour("#ff9900");
console.log(c.lighten(0.2).toHex()); // "#ffb34d"
console.log(c.isDark()); // false
console.log(c.contrast("#ffffff")); // WCAG contrast ratio
