What is colord?
The colord npm package is a tiny yet powerful tool for color conversions and manipulations. It provides functions for parsing colors, converting them between different color models, and manipulating their properties such as hue, saturation, lightness, and alpha channel.
What are colord's main functionalities?
Parsing and converting colors
This feature allows you to parse color strings and convert them to different color models. The example shows how to parse a hex color and convert it to an RGB object.
const { colord, extend } = require('colord');
const c = colord('#ff5733');
console.log(c.toRgb()); // { r: 255, g: 87, b: 51, a: 1 }
Manipulating color properties
This feature enables you to manipulate color properties such as alpha channel. The example demonstrates setting the alpha of an RGBA color and converting it to a string.
const { colord } = require('colord');
const color = colord('rgba(255, 87, 51, 1)');
console.log(color.alpha(0.5).toRgbString()); // 'rgba(255, 87, 51, 0.5)'
Mixing colors
This feature allows you to mix two colors together. The example mixes a color with white at a 50% ratio and outputs the hex value of the result.
const { colord } = require('colord');
const mix = colord('#ff5733').mix('#ffffff', 0.5).toHex();
console.log(mix); // '#ffaba9'
Generating readable colors
This feature helps in checking if a color is readable on another color, which is useful for accessibility. The example checks if the color '#ff5733' is readable on a white background.
const { colord, extend } = require('colord');
extend([require('colord/plugins/a11y')]);
const color = colord('#ff5733');
console.log(color.isReadable('#ffffff')); // true or false
