~10 KB gzipped.

Installation

To install the Colore library, use the follow command:

npm install colore-js

Alternatively, if you use Yarn:

yarn add colore-js

Getting Started

import { hexToRgb, lightenColor, saturateColor, setCssVariableValue } from 'colore-js';

// Lightening a color
const lightenedRgb = lightenColor('rgb(255, 0, 0)', 20);
console.log(lightenedRgb); // Output: 'rgb(255, 51, 51)'

// Saturating a color
const saturatedRgb = saturateColor('rgb(255, 0, 0)', 50);
console.log(saturatedRgb); // Output: 'rgb(255, 51, 51)'

// Converting HEX to RGB color format
const rgbString = hexToRgb('#ff5733');
console.log(rgbString); // Output: 'rgb(255, 87, 51)'

// Setting a new CSS Variable Value
const element = document.querySelector('.my-element');
setCssVariableValue(element, '--my-variable', 'blue');
