# HSL<sub>uv</sub> - Human-friendly HSL
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
Client-side: download [the latest hsluv.min.js](https://github.com/hsluv/hsluv/tree/master/javascript/dist).
|
||
|
|
|
||
|
|
Once this module is loaded in the browser, you can access it via the
|
||
|
|
global ``window.hsluv``.
|
||
|
|
|
||
|
|
Server-side: ``npm install hsluv``.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Most functions take tuples, ie: Javascript arrays with three elements. Make sure you are using
|
||
|
|
`func([a,b,c])` and not `func(a,b,c)`. If you are getting NaN for output then this is probably
|
||
|
|
the problem.
|
||
|
|
|
||
|
|
**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.
|
||
|
|
|
||
|
|
For advance use cases, additional functions are avalible:
|
||
|
|
|
||
|
|
**hsluvToLch**, **lchToHsluv**
|
||
|
|
|
||
|
|
**hpluvToLch**, **lchToHpluv**
|
||
|
|
|
||
|
|
**rgbToXyz**, **xyzToRgb**
|
||
|
|
|
||
|
|
**rgbToLch**, **lchToRgb**
|
||
|
|
|
||
|
|
**luvToXyz**, **xyzToLuv**
|
||
|
|
|
||
|
|
**lchToLuv**, **luvToLch**
|
||
|
|
