API

Color parsing

colord(input)

Parses the given input and creates a new Colord instance. String parsing strictly conforms to CSS Color Level Specifications.

import { colord } from "colord";

// String input examples
colord("#FFF");
colord("#ffffff");
colord("#ffffffff");
colord("rgb(255, 255, 255)");
colord("rgba(255, 255, 255, 0.5)");
colord("rgba(100% 100% 100% / 50%)");
colord("hsl(90, 100%, 100%)");
colord("hsla(90, 100%, 100%, 0.5)");
colord("hsla(90deg 100% 100% / 50%)");
colord("tomato"); // requires "names" plugin

// Object input examples
colord({ r: 255, g: 255, b: 255 });
colord({ r: 255, g: 255, b: 255, a: 1 });
colord({ h: 360, s: 100, l: 100 });
colord({ h: 360, s: 100, l: 100, a: 1 });
colord({ h: 360, s: 100, v: 100 });
colord({ h: 360, s: 100, v: 100, a: 1 });

Check out the "Plugins" section for more input format examples.

getFormat(input)

Returns a color model name for the input passed to the function. Uses the same parsing system as colord function.

import { getFormat } from "colord";

getFormat("#aabbcc"); // "hex"

getFormat("hsl(180deg, 50%, 50%)"); // "hsl"
getFormat("WUT?"); // undefined

Color conversion

.toHex()

colord("#ffffff").isValid(); // true
colord("#wwuutt").isValid(); // false
colord("abracadabra").isValid(); // false
colord({ r: 0, g: 0, b: 0 }).isValid(); // true
colord({ r: 0, g: 0, v: 0 }).isValid(); // false

.isEqual(color2)

Determines whether two values are the same color.

colord("#000000").isEqual("rgb(0, 0, 0)"); // true
colord("#000000").isEqual("rgb(255, 255, 255)"); // false

.alpha()

colord("#ffffff").alpha(); // 1
colord("rgba(50, 100, 150, 0.5)").alpha(); // 0.5

.hue()

colord("hsl(90, 50%, 50%)").hue(); // 90
colord("hsl(-10, 50%, 50%)").hue(); // 350

.brightness()

Returns the brightness of a color (from 0 to 1). The calculation logic is modified from Web Content Accessibility Guidelines.

colord("#000000").brightness(); // 0
colord("#808080").brightness(); // 0.5
colord("#ffffff").brightness(); // 1

.isLight()

Checks that a background and text color pair is readable according to WCAG 2.0 Contrast and Color Requirements.

colord("#000000").isReadable(); // true (normal black text on white bg conforms to WCAG AA)
colord("#777777").isReadable(); // false (normal gray text on white bg conforms to WCAG AA)
colord("#ffffff").isReadable("#000000"); // true (normal white text on black bg conforms to WCAG AA)
colord("#e60000").isReadable("#ffff47"); // true (normal red text on yellow bg conforms to WCAG AA)

colord("#e60000").isReadable("#ffff47", { level: "AAA", size: "large" }); // true (large red text on yellow bg conforms to WCAG AAA)

.delta(color2 = "#FFF") (lab plugin)

Calculates the perceived color difference between two colors. The difference calculated according to Delta E2000. The return value is 0 if the colors are equal, 1 if they are entirely different.

colord("#3296fa").delta("#197dc8"); // 0.099
colord("#faf0c8").delta("#ffffff"); // 0.148
colord("#afafaf").delta("#b4b4b4"); // 0.014
colord("#000000").delta("#ffffff"); // 1

extend([labPlugin]);

colord({ l: 53.24, a: 80.09, b: 67.2 }).toHex(); // "#ff0000"
colord("#ffffff").toLab(); // { l: 100, a: 0, b: 0, alpha: 1 }

colord("#afafaf").delta("#b4b4b4"); // 0.014
colord("#000000").delta("#ffffff"); // 1

lch (CIE LCH color space) 1.3 KB

Adds support of CIE LCH color space. The conversion logic is ported from CSS Color Module Level 4 Specification.

import { colord, extend } from "colord";
import lchPlugin from "colord/plugins/lch";

extend([lchPlugin]);

colord({ l: 100, c: 0, h: 0 }).toHex(); // "#ffffff"
colord("lch(48.25% 30.07 196.38)").toHex(); // "#008080"

colord("#646464").toLch(); // { l: 42.37, c: 0, h: 0, a: 1 }
colord("#646464").alpha(0.5).toLchString(); // "lch(42.37% 0 0 / 0.5)"

minify (Color string minification) 0.5 KB

A plugin adding color string minification utilities.

import { colord, extend } from "colord";
import minifyPlugin from "colord/plugins/minify";

extend([minifyPlugin]);

colord("black").minify(); // "#000"
colord("#112233").minify(); // "#123"
colord("darkgray").minify(); // "#a9a9a9"
colord("rgba(170,170,170,0.4)").minify(); // "hsla(0,0%,67%,.4)"
colord("rgba(170,170,170,0.4)").minify({ alphaHex: true }); // "#aaa6"

mix (Color mixing) 0.96 KB

A plugin adding color mixing utilities.

In contrast to other libraries that perform RGB values mixing, Colord mixes colors through LAB color space. This approach produces better results and doesn't have the drawbacks the legacy way has.

→ Online demo

import { colord, extend } from "colord";
import mixPlugin from "colord/plugins/mix";

extend([mixPlugin]);

colord("#ffffff").mix("#000000").toHex(); // "#777777"
colord("#800080").mix("#dda0dd").toHex(); // "#af5cae"
colord("#cd853f").mix("#eee8aa", 0.6).toHex(); // "#e3c07e"
colord("#008080").mix("#808000", 0.35).toHex(); // "#50805d"

Also, the plugin provides special mixtures such as tints, shades, and tones:

const color = colord("#ff0000");
color.tints(3).map((c) => c.toHex()); // ["#ff0000", "#ff9f80", "#ffffff"];
color.shades(3).map((c) => c.toHex()); // ["#ff0000", "#7a1b0b", "#000000"];
color.tones(3).map((c) => c.toHex()); // ["#ff0000", "#c86147", "#808080"];

names (CSS color keywords) 1.45 KB

Provides options to convert a color into a CSS color keyword and vice versa.

import { colord, extend } from "colord";
import namesPlugin from "colord/plugins/names";

extend([namesPlugin]);

colord("tomato").toHex(); // "#ff6347"
colord("#00ffff").toName(); // "cyan"
colord("rgba(0, 0, 0, 0)").toName(); // "transparent"
colord("#fe0000").toName(); // undefined (the color is not specified in CSS specs)
colord("#fe0000").toName({ closest: true }); // "red" (closest color)

xyz (CIE XYZ color space) 0.7 KB

Adds support of CIE XYZ color model. The conversion logic is ported from CSS Color Module Level 4 Specification.

import { colord, extend } from "colord";
import xyzPlugin from "colord/plugins/xyz";

extend([xyzPlugin]);

colord("#ffffff").toXyz(); // { x: 95.047, y: 100, z: 108.883, a: 1 }
colord({ x: 0, y: 0, z: 0 }).toHex(); // "#000000"

Types

Colord is written in strict TypeScript and ships with types in the library itself — no need for any other install. We provide everything you need in one tiny package.

While not only typing its own functions and variables, Colord can also help you type yours. Depending on the color space you are using, you can also import and use the type that is associated with it.

import { RgbColor, RgbaColor, HslColor, HslaColor, HsvColor, HsvaColor } from "colord";

const foo: HslColor = { h: 0, s: 0, l: 0 };
const bar: RgbColor = { r: 0, g: 0, v: 0 }; // ERROR
