## Description

Apply filters to colors to simulate things like color blindness and night vision. This
library tries to simulate the behavior of the svg filter effect 
[feColorMatrix](https://developer.mozilla.org/en-US/docs/Web/SVG/Element/feColorMatrix).

It comes in 2 formats: [a node.js library](#getting-started) and a
[command line tool](#command-line-tool).

## Examples

Usage and output examples can be found here:

- http://projects.skratchdot.com/color-matrix/examples.html

## Node.js Library

### Getting Started

Install the module with: `npm install color-matrix`

```javascript
var ColorMatrix = require('color-matrix').ColorMatrix;
var matrix = new ColorMatrix();
// simulate color-blindness
matrix.transform([222, 0, 173, 255], 'deuteranopia'); // returns [139, 155, 121, 1]
```

***NOTE:*** For a better "color blindness" library, see:
[color-blind](http://github.com/skratchdot/color-blind). This library is just a port
of the old "color matrix" code for use in node.  It does allow you to pass in custom
filters (which is why I published it, instead of throwing it away).

### API Documentation

Read the [API Docs](http://projects.skratchdot.com/color-matrix/api.html)
