HSLuv is a perceptually-uniform alternative to HSL. Here is some
Stylus code that generates 6 tiles with well-contrasting
complementary colors:

``Stylus
tile(hue)
background-color hsluv(hue, 90%, 80%)
color hsluv(hue + 190deg, 90%, 10%)

for hue in 0deg 30deg 60deg 90deg 120deg 150deg
.colored-tile-{hue}
tile(hue)
`

Usage

Install the plugin:

`Shell
npm install hsluv-stylus
`

To use from command line, run stylus like this:

`Shell
stylus -u hsluv-stylus < input.styl
`

To use programmatically, do this:

`JavaScript
var stylus = require('stylus');
var hsluvStylus = require('hsluv-stylus');

function renderWithHsluv(str) {
return stylus(str).use(hsluvStylus()).render();
}
``

This module adds two following two Stylus functions that let you specify colors using HSLuv and its
pastel variant HPLuv:

hsluv(H, S, L, [A])

hpluv(H, S, L, [A])

H represents hue as a number between 0 and 360, S represents saturation as a number between 0 and
100 and L represents lightness as a number between 0 and 100. A is an optional value between 0 and
1 representing the alpha channel.
