[![Build Status](https://travis-ci.org/hsluv/hsluv-python.svg?branch=master)](https://travis-ci.org/hsluv/hsluv-python)
[![Package Version](https://img.shields.io/pypi/v/hsluv.svg)](https://pypi.python.org/pypi/hsluv/)

A Python implementation of [HSLuv](https://www.hsluv.org) (revision 4).

## Installation

`pip install hsluv`

## Usage

> This library does not hide (clamp) floating point error, e.g. you might receive a value outside
> of the expected range. If you wish to display the outputs of this library, consider rounding them 
> for your purpose. The floating point error has not been quantified, but at least 10 decimal digits 
> should be free of it.

### `hsluv_to_hex([hue, saturation, lightness])`

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

### `hsluv_to_rgb([hue, saturation, lightness])`

Like above, but returns a list of 3 floats between 0 and 1, for each RGB channel.

### `hex_to_hsluv(hex)`

Takes a hex string and returns the HSLuv color as a list of floats as defined above.

### `rgb_to_hsluv([red, green, blue])`

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

For HPLuv (the pastel variant), use `hpluv_to_hex`, `hpluv_to_rgb`, `hex_to_hpluv` and `rgb_to_hpluv`.

## Testing

Run `python setup.py test`.
