[](https://github.com/hsluv/hsluv-python/actions/workflows/test.yml)
[](https://pypi.python.org/pypi/hsluv/)
A Python implementation of [HSLuv](https://www.hsluv.org) (revision 4).
## Installation
`pip install hsluv`
Python 2 users: `pip install hsluv==5.0.0`
## 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`.
