![Lookup Table](https://raw.github.com/hughsk/lut/master/image.png)

Renders [RGB lookup tables](http://the-witness.net/news/2012/08/fun-with-in-engine-color-grading/) to a canvas element.

## Installation ##

``` bash

npm install lut

```

## Usage ##

`lut(red, green, blue, canvas)`

``` javascript

var lut = require('lut')

  , canvas = document.createElement('canvas')

// Defaults to 32x32x32, creating a new canvas element:

document.body.appendChild(lut())

// But you can render on top of an existing canvas,

// and specify the resolution (number of shades) for

// each colour too:

document.body.appendChild(canvas)

lut(64, 8, 128, canvas)

```
