HSLuv - Human-friendly HSL

Installation

Client-side: download the latest hsluv.min.js from the releases page.

Once this module is loaded in the browser, you can access it via the global window.hsluv.

Server-side: npm install hsluv.

Usage

hsluvToHex([hue, saturation, lightness])

hue is a number between 0 and 360, saturation and lightness are numbers between 0 and 100. This function returns the resulting color as a hex string.

hsluvToRgb([hue, saturation, lightness])

Like above, but returns an array of 3 numbers between 0 and 1, for the r, g, and b channel.

hexToHsluv(hex)

Takes a hex string and returns the HSLuv color as array that contains the hue (0-360), saturation(0-100) and lightness(0-100) channel. Note: The result can have rounding errors. For example saturation can be 100.00000000000007

rgbToHsluv([red, green, blue])

Like above, but red, green and blue are passed as numbers between 0 and 1.

Use hpluvToHex, hpluvToRgb, hexToHpluv and rgbToHpluv for the pastel variant (HPLuv). Note that HPLuv does not contain all the colors of RGB, so converting arbitrary RGB to it may generate invalid HPLuv colors.

HSLuv can also be used as a Stylus plugin. See here.
