convert-web-colors is a web color conversion library for JavaScript and node. It supports conversion between rgb, hsl and hex strings, both with and without alpha channels (transparency).

Install

$ npm i -S convert-web-colors

Usage

Just provide a string or array in one of the supported formats:

var converter = require('convert-web-colors');

var colors = converter.convert('rgb(120,113,54)'); // converter.convert([120,113,54]) would return the same result

var rgb  = colors.rgb;  // rgb(120, 113, 54)
var rgba = colors.rgba; // rgba(120, 113, 54, 1)

var hsl  = colors.hsl;  // hsl(53.6, 37.9%, 34.1%)
var hsla = colors.hsla; // hsla(54, 37.9%, 34.1%, 1)

var hex  = colors.hex;  // #787136
var hexa = colors.hexa; // #787136FF

Arrays

By default, an object containing color values as strings will be returned. If you want to receive values as arrays instead, pass in an object as the second parameter with a property: returnArrays: true;

var converter = require('convert-web-colors');

var colors = converter.convert('rgb(120,113,54)', { returnArrays: true });

var rgb  = colors.rgb;  // [120, 113, 54]
var rgba = colors.rgba; // [120, 113, 54, 1]

var hsl  = colors.hsl;  // [54, 37.9, 34.1]
var hsla = colors.hsla; // [53.6, 37.9, 34.1, 1]

var hexa = colors.hexa; // #787136FF
var hex  = colors.hex;  // #787136
