API
Color parsing
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.
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({ r: 13, g: 237, b: 162, a: 0.5 }); // "rgb"
getFormat("hsl(180deg, 50%, 50%)"); // "hsl"
getFormat("WUT?"); // undefined
Color conversion
Returns the hexadecimal representation of a color. When the alpha channel value of the color is less than 1, it outputs #rrggbbaa
format instead of #rrggbb
.
colord("rgb(0, 255, 0)").toHex(); // "#00ff00"
colord({ h: 300, s: 100, l: 50 }).toHex(); // "#ff00ff"
colord({ r: 255, g: 255, b: 255, a: 0 }).toHex(); // "#ffffff00"
colord("#ff0000").toRgb(); // { r: 255, g: 0, b: 0, a: 1 }
colord({ h: 180, s: 100, l: 50, a: 0.5 }).toRgb(); // { r: 0, g: 255, b: 255, a: 0.5 }
colord("#ff0000").toRgbString(); // "rgb(255, 0, 0)"
colord({ h: 180, s: 100, l: 50, a: 0.5 }).toRgbString(); // "rgba(0, 255, 255, 0.5)"
Converts a color to HSL color space and returns an object.
colord("#ffff00").toHsl(); // { h: 60, s: 100, l: 50, a: 1 }
colord("rgba(0, 0, 255, 0.5) ").toHsl(); // { h: 240, s: 100, l: 50, a: 0.5 }
Converts a color to HSL color space and expresses it through the functional notation.
colord("#ffff00").toHslString(); // "hsl(60, 100%, 50%)"
colord("rgba(0, 0, 255, 0.5)").toHslString(); // "hsla(240, 100%, 50%, 0.5)"

Color analysis
Returns a boolean indicating whether or not an input has been parsed successfully. Note: If parsing is unsuccessful, Colord defaults to black (does not throws an error).
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
Determines whether two values are the same color.
colord("#000000").isEqual("rgb(0, 0, 0)"); // true
colord("#000000").isEqual("rgb(255, 255, 255)"); // false
colord("#ffffff").alpha(); // 1
colord("rgba(50, 100, 150, 0.5)").alpha(); // 0.5
colord("hsl(90, 50%, 50%)").hue(); // 90
colord("hsl(-10, 50%, 50%)").hue(); // 350
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
Same as calling brightness() >= 0.5
.
colord("#111111").isLight(); // false
colord("#aabbcc").isLight(); // true
colord("#ffffff").isLight(); // true
Same as calling brightness() < 0.5

colord("#808080").luminance(); // 0.22
colord("#ccddee").luminance(); // 0.71
colord("#ffffff").luminance(); // 1
Calculates a contrast ratio for a color pair. This luminance difference is expressed as a ratio ranging from 1 (e.g. white on white) to 21 (e.g., black on a white). WCAG Accessibility Level AA requires a ratio of at least 4.5 for normal text and 3 for large text.
colord("#000000").contrast(); // 21 (black on white)
colord("#ffffff").contrast("#000000"); // 21 (white on black)

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" }); // false (normal red text on yellow bg does not conform to WCAG AAA)
colord("#e60000").isReadable("#ffff47", { level: "AAA", size: "large" }); // true (large red text on yellow bg conforms to WCAG AAA)
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

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"
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.
β 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"];
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)
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 β 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
